Abstract
A green and efficient protocol for the preparation of benzo[a]carbazoles via visible-light-promoted and electron donor-acceptor (EDA) complex-driven intermolecular cyclization of 2-arylindoles with Z-α-bromocinnamaldehydes in the absence of external photocatalysts, transition metals, and oxidants was reported. This new approach demonstrates an intermolecular cyclization model using indole derivatives as electron donors under visible light. Mechanistic investigations have showed that 2-arylindoles with Z-α-bromocinnamaldehydes form EDA complexes, which undergo sequential single-electron transfer, radical coupling, 6π-electrocyclization, and dehydroaromatization to generate benzo[a]carbazoles under visible light irradiation. The current photochemical method features readily accessible starting materials, mild conditions, simple operation, and a broad substrate scope.

Abstract
A photoinduced deuterodetriazenation of aryltriazenes with CDCl3 under catalyst-free conditions is reported. The reactions featured simple operation, ecofriendly conditions, readily available reagents, inexpensive D sources, precise site selectivity, and a wide range of substrates. Since aryltriazenes could be readily synthesized from arylamine, this protocol can be used as a general method for easily and accurately incorporating deuterium into aromatic systems by using CDCl3 as a D source.

Abstract
An efficient palladium-catalyzed region-selective C7-trifluoromethylation of indolines using commercially available Umemoto's reagent was reported. The reaction utilizing Umemoto's reagent as CF3 radical precursor, pyrimidine as a removable directing group, Pd(II) as a catalyst, and Cu(II) as an oxidant furnished the required products with excellent regioselectivities and good yields. The present strategy has good region-selectivity, broad substrate scope, and scale-up application. Additionally, the present method was underlined by the direct C-1 trifluoromethylation of carbazoles. Furthermore, C7 trifluoromethylated indole can also be easily obtained via Pd-catalyzed direct C-7 trifluoromethylation/oxidation/deprotection sequential reactions.

Abstract
A palladium-catalyzed direct C-H arylation of indolines at C-7 position has been achieved at near-ambient temperature. The reaction was carried out with aryltriazene as a stable aryl source and electron shuttle to sustainably release aryl radical in situ under the action of promoter, and pyrimidine as a detachable directing group for the synthesis of 7-arylindolines under oxidant- and ligand-free conditions. Notably, this catalytic system can also be applied to the direct and site-selective arylation of tetrahydroquinolines (C-8) and carbazoles (C-1).

Abstract
A visible-light-promoted [3 + 2] cyclization between chalcones and 2-mercaptobenzoimidazoles for the construction of diverse imidazo[2,1-b]thiazoles via an electron-donor-acceptor (EDA) complex has been developed. This novel aminothiolation can be realized under only visible light irradiation without the aid of external photocatalysts, transition metals, and oxidants. Mechanistic investigations have revealed that the thiol anions and chalcones form EDA complexes, providing a novel strategy for the synthesis of imidazo[2,1-b]thiazoles.

Abstract
We report a direct and green electrochemical oxidative cross-dehydrogenative coupling reaction of N-heterocycles with hydrogen phosphoryl compounds under external oxidant-free conditions. Various phosphorylation products of substituted carbazoles and indoles are assembled in modest to excellent yields. A hydrogen release process is preliminarily demonstrated and H2 is the sole byproduct. An imidazolium based ionic liquid is selected as the optimal electrolyte.

Abstract
A practical and switchable method for the synthesis of aryl sulfones and sulfoxides via sulfide oxidation was developed. The chemoselectivities of products were simply controlled by reaction temperature using O2/air as the terminal oxidant and oxygen source. The broad substrate scope, easy realization of gram-scale production, and the simplification of a sulfide oxidation system render the strategy attractive and valuable.

Abstract
The hydration of nitriles to amides in a water extract of pomelo peel ash (WEPPA) was realized with moderate to excellent yields without using external transition metals, bases or organic solvents. This reaction features a broad substrate scope, wide functional group tolerance, prominent chemoselectivity, and good reusability. Notably, a magnification experiment in this bio-based solvent at 100 mmol further demonstrated its practicability.

Abstract
Due to special properties of ILs (Ionic Liquids) like their wide liquid range, good solvating ability, negligible vapour pressure, non-inflammability, environment friendly medium, high thermal stability, easy recycling and rate promoters etc. they are used in organic synthesis. The investigation for the replacement of organic solvents in organic synthesis is a growing area of interest due to increasing environmental issues. Therefore, ionic liquids have attracted the attention of chemists and act as a catalyst and reaction medium in organic reaction with high activity. There is no doubt that ionic liquids have become a major subject of study for modern chemistry. In comparison to traditional processes the use of ionic liquids resulted in improved, complimentary or alternative selectivities in organic synthesis. The present manuscript reported the synthesis of multiple nitrogen containing five-membered heterocyclic compounds using ionic liquids. This review covered interesting discoveries in the past few years.

Abstract
A [Cp*RhIII ]-catalyzed direct C-H amidation is carried out in ionic liquid. Both C(sp2 )-H bonds of (hetero)arenes and alkenes and unactivated C(sp3 )-H bonds can be easily amidated with high functional-group tolerance and excellent yields under these conditions. Notably, using [Cp*RhIII ]/[BMIM]BF4 (BMIM=1-butyl-3-methylimidazolium) as the green and recyclable medium is environmentally benign, in light of characteristics such as the reusability of the expensive rhodium catalyst, avoidance of highly toxic organic solvents, and mild reaction conditions, as well as a short reaction time.

Abstract
A simple and versatile method for the preparation of linear, trisubstituted triazenes is reported. The procedure is based on the reaction of Grignard reagents with 1-azido-4-iodobutane or 4-azidobutyl-4-methylbenzenesulfonate. These organic azides enable the regioselective formation of triazenes via an intramolecular cyclization step. The new method can be used for the preparation of aryl, heteroaryl, vinyl, and alkyl triazenes. The synthetic utility of vinyl triazenes is demonstrated by acid-induced C-N, C-O, C-F, C-P, and C-S bond-forming reactions.

Abstract
Tetraphenylmethane-ethynylene-based shape-persistent dendrimers are a new class of nanoobjects with an intriguing 3D architecture. We report an efficient divergent strategy for their synthesis based on the Sonogashira Pd-catalyzed coupling of terminal alkynes with aryl iodides. As repeat unit, we prepared a tetraphenylmethane derivative bearing a terminal alkyne and three triazene moieties. Coupling of this building block to tetrakis(p-iodophenyl)methane afforded, after triazene activation, a dodecaiodo-terminated first generation dendrimer, which was transformed by another Sonogashira coupling into a methoxy-terminated second generation dendrimer with persistent globular shape and well-defined cavities. This work also unveils new aspects of triazene chemistry, i.e., the unprecedented efficient generation of an azo compound by mixing of a triazene with phenol.
