Abstract
We report a mild method for the copper-catalyzed amination of aryl chlorides. Key to the success of the method was the use of highly sterically encumbered N1,N2-diaryl diamine ligands which resist catalyst deactivation, allowing reactions to proceed at significantly lower temperatures and with a broader scope than current protocols. A sequence of highly chemoselective C-N and C-O cross-coupling reactions were demonstrated, and mechanistic studies indicate that oxidative addition of the Cu catalyst to the aryl chlorides is rate-limiting. We anticipate that the design principles disclosed herein will help motivate further advances in Cu-catalyzed transformations of aryl chlorides.

Abstract
A general and efficient CuI/N-carbazolyl-1H-pyrrole-2-carbohydrazide catalyst system was developed for the N-arylation of cyclopropylamine using aryl bromides at room temperature. Herein, 5 mol % CuI and 5 mol % of the ligand were used to synthesize N-aryl cyclopropylamines in moderate to excellent yields. This protocol was scaled up to produce the desired product at gram levels and has been generalized for C-N coupling between aryl bromides and amines at room temperature.

Abstract
It has been shown that cheap and easily available N,N'-diaryldihydrophenazines can successfully replace Ir(III)- and Ru(II)-based photocatalysts in the dual photoredox/Ni(II) C-N coupling of aryl halides with a wide range of anilines (32 examples). The efficient, operationally simple approach to diarylamines has been elaborated, which is amenable to scaling up via a flow apparatus.

Abstract
Development of C-N coupling methodologies based on Earth-abundant metals is a promising strategy in homogeneous catalysis for sustainable processes. However, such systems suffer from deactivation and low catalytic activity. We here report that encapsulation of Cu(I) within the phenanthroyl-containing calix[8]arene derivative 1,5-(2,9-dimethyl-1,10-phenanthroyl)-2,3,4,6,7,8-hexamethyl-p-tert-butylcalix[8]arene (C8PhenMe6 ) significantly enhances C-N coupling activity up to 92 % yield in the reaction of aryl halides and aryl amines, with low catalyst loadings (2.5 % mol). A tailored multiscale computational protocol based on Molecular Dynamics simulations and DFT investigations revealed an oxidative addition/reductive elimination process of the supramolecular catalyst [Cu(C8PhenMe6)I]. The computational investigations uncovered the origins of the enhanced catalytic activity over its molecular analogues: Catalyst deactivation through dimerization is prevented, and product release facilitated. Capturing the dynamic profile of the macrocycle and the impact of non-covalent interactions on reactivity allows for the rationalization of the behavior of the flexible supramolecular catalysts employed.

Abstract
Aims:
This work aims to widen the scope of methodologies to prepare functionalized
N-alkenylcarbazates.
Background:
Alkenylcarbazates are generally prepared via Aza-Baylis-Hillman reactions, nucleophilic
attack on ketones or a tandem carbometallation/amidation reaction of alkynes.
Objective:
The objective of this work is to develop a method to prepare functionalized Nalkenylcarbazates
that alleviates the problem encountered in the above methods (use of electron
deficient alkenes, use of stoiechiometric amounts of metal, access to symmetrical dicarbazates only).
Methods:
Use of copper-catalyzed cross-coupling between vinylic diiodide and carbazates to prepare
functionalized N-alkenylcarbazates.
Results:
Various β-iodovinylcarbazates were synthesized with up to good yields. The highest
yields were obtained using dicarbazates. Functionalization of β-iodovinylcarbazate demonstrated
that the vinyl iodide moiety of these molecules can be substituted by a variety of functional
groups via transition metal-catalyzed coupling reactions.
Conclusion:
Copper-catalyzed cross-coupling reaction is efficient to prepare functionalized
N-alkenylcarbazates.

Abstract
An efficient ruthenium-catalyzed N-alkylation of amines, amides and sulfonamides has been developed employing novel pentamethylcyclopentadienylruthenium(II) complexes bearing the methylene linked bis(NHC) ligand bis(3-methylimidazol-2-ylidene)methane. The acetonitrile complex 2 has proven particularly effective with a broad range of substrates with low catalyst loading (0.1-2.5 mol%) and high functional group tolerance under mild conditions. A total of 52 N-alkylated organonitrogen compounds including biologically relevant scaffolds were synthesized from (hetero)aromatic and aliphatic amines, amides and sulfonamides using alcohols or diols as alkylating agents in up to 99% isolated yield, even on gram-scale reactions. In the case of sulfonamides, it is the first example of N-alkylation employing a transition-metal complex bearing NHC ligands.

Abstract
Fluorescein and its analogues have found only limited use in biological imaging because of the poor photostability and cell membrane impermeability of their O-unprotected forms. Herein, we report rationally designed N-cyanorhodamines as orange- to red-emitting, photostable and cell-permeant fluorescent labels negatively charged at physiological pH values and thus devoid of off-targeting artifacts often observed for cationic fluorophores. In combination with well-established fluorescent labels, self-labelling protein (HaloTag, SNAP-tag) ligands derived from N-cyanorhodamines permit up to four-colour confocal and super-resolution STED imaging in living cells. N-Cyanorhodamines – photostable, cell-permeant analogues of fluoresceins – provide fast labelling kinetics with the HaloTag protein and background-free images in multicolour super-resolution microscopy.![]()

Abstract
A new methodology to synthesize sulfonyl-N-phenylaniline derivatives via the trapping of bromo-sulfone derivatives generated from N-tosylhydrazones (NTHs) with amines is described. The reaction proved successful for a wide range of NTHs and amines and tolerated various functional groups on either coupling partner (35 examples). The mechanism was studied, and we showed that the sulfone formation does not follow a radical pathway.

Abstract
A one-pot and step economic reaction involving Rh(III)-catalyzed C-H thiolation and relay Cu(II)-catalyzed C-N amination of acetanilide and 2-bromothiophenol is reported here, with several valuable phenothiazine products obtained. This synthesis protocol proceeds from easily starting materials, demonstrating high atom economy, broad substrate scope, and good yield. Furthermore, the directing group can be easily eliminated, and chlorpromazine is provided in a large scale; thus this synthesis protocol could be utilized to construct phenothiazine scaffolds.

Abstract
We report here the use of eucalyptol as a bio-based solvent for the Buchwald–Hartwig reaction on O,S,N-heterocycles. These heterocycles containing oxygen, sulfur and nitrogen were chosen as targets or as starting materials. Once again, eucalyptol demonstrated to be a possible sustainable alternative to common solvents.

Abstract
![]()
Spectral stability
of small-molecule fluorescent probes is required
for correct interpretation and reproducibility of multicolor fluorescence
imaging data, in particular under high (de)excitation light intensities
of super-resolution imaging or in single-molecule applications. We
propose a synthetic approach to a series of spectrally stable rhodamine
fluorophores based on sequential Ru- and Cu-catalyzed transformations,
evaluate their stability against photobleaching and photoconversion
in the context of other fluorophores using chemometric analysis, and
demonstrate chemical reactivity of fluorophore photoproducts. The
substitution patterns providing the photoconversion-resistant triarylmethane
fluorophores have been identified, and the applicability of nonbluing
labels in live-cell STED nanoscopy is demonstrated.

Abstract
Efficient C-S and C-N cross-coupling reactions have been developed for regioselective, scalable
and environmentally benign synthesis of substituted phenothiazine derivatives. Cross-coupling reactions
were demonstrated on various challenging substrates using non-toxic, highly economical, readily
available ferric citrate as a catalyst to get desired product with high regioselectivity. Atom economy
is the added advantage of this protocol since additional N-protection step before coupling and eventual
deprotection of the same to obtain the desired product arenot required. To the best of our knowledge,
this is the first report on the use of inexpensive ferric citrate as a catalyst without involving any ligand
for the synthesis of regioselectively substituted phenothiazine.

Abstract
Various 2-amino-3-cyanoindoles are synthesized through copper catalyzed intramolecular N-arylations of ketene aminals at room temperature for the first time with 60-99% yields within 0.1-2 h. Controlled regioselective N-arylations of unsymmetrical ketene aminals are also studied. Further, a new double heteroannulation approach is demonstrated for the synthesis of 11-aminoindolo[2,3- b]quinolines from acyclic and nonheterocyclic precursors.

Abstract
Along with amide bond formation, Suzuki cross-coupling, and reductive amination, the Buchwald-Hartwig-Ullmann-type amination of aryl halides stands as one of the most employed reactions in modern medicinal chemistry. The work herein demonstrates the potential of utilizing electrochemistry to provide a complementary avenue to access such critical bonds using an inexpensive nickel catalyst under mild reaction conditions. Of note is the scalability, functional-group tolerance, rapid rate, and the ability to employ a variety of aryl donors (Ar-Cl, Ar-Br, Ar-I, Ar-OTf), amine types (primary and secondary), and even alternative X-H donors (alcohols and amides).
