Abstract
Dithioacetals are a frequently used motif in synthetic organic chemistry, and most existing reports discuss only symmetrical dithioacetals. Examples of unsymmetrical dithioacetals are scarce, and few general methods for the selective synthesis of these compounds exists. An intriguing visible-light-induced strategy has been established in this work for sequential reactions of S-H insertion and acetal exchange between acylsilanes and two different thiols that deliver a wide variety of unsymmetrical dithioacetals in moderate yields. The unsymmetrical dithioacetals were obtained with high selectivity, and a great variety of functional groups were tolerated.

Abstract
Simultaneous multiple displacements of organic molecules can lead to a large structural reconstruction with increased complexity that would be difficult to access otherwise. Whereas double displacement such as olefin metathesis is well-established, higher-order versions remain much more challenging, because of their intrinsic thermodynamic disadvantages. Here, we describe a newly discovered relayed heteroatom group transfer process between bisthioesters and triaminophosphines as an unusual example of a formal triple displacement. Through the oxygen/nitrogen exchange between the two simple starting materials, in addition to the 1,2-sulfur migration of a putative carbene intermediate, an organized relocation of the O/S/N groups proceeded to give a variety of α,α-disulfenylamides with excellent efficiency under ambient conditions. The experimental and computational mechanistic studies revealed the sequence of the relayed group shifts via an α,α-disulfenyl phosphonium enolate intermediate as well as the dual role of triaminophosphine as both an oxygen acceptor and a nitrogen donor.

Abstract
![]()
Zwitterionic adducts
of N-heterocyclic carbene and carbodiimide
(NHC-CDI) are an emerging class of organic compounds with promising
properties for applications in various fields. Herein, we report the
use of the ICyCDI(p-Tol) betaine adduct (1a) and its cationic derivatives 2a and 3a as catalyst precursors for the dichloromethane valorization via
transformation into high added value products CH2Z2 (Z = OR, SR or NR2). This process implies selective
chloride substitution of dichloromethane by a range of nucleophiles
Na+Z– (preformed or generated in situ from HZ and an inorganic base) to yield formaldehyde-derived
acetals, dithioacetals, or aminals with full selectivity. The reactions
are conducted in a multigram-scale under very mild conditions, using
dichloromethane both as a reagent and solvent, and very low catalyst
loading (0.01 mol %). The CH2Z2 derivatives
were isolated in quantitative yields after filtration and evaporation,
which facilitates recycling the dichloromethane excess. Mechanistic
studies for the synthesis of methylal CH2(OMe)2 rule out organocatalysis as being responsible for the CH2 transfer, and a phase-transfer catalysis mechanism is proposed instead.
Furthermore, we observed that 1a and 2a react
with NaOMe to form unusual isoureate ethers, which are the actual
phase-transfer catalysts, with a strong preference for sodium over
other alkali metal nucleophiles.

Abstract
Dithioacetals are a frequently used motif in synthetic organic chemistry and have recently seen increasing attention as structural motif in promising antiviral agents against plant pathogens. Most existing reports, however, only discuss symmetrical dithioacetals. Examples of mixed dithioacetals are scarce and no general method for the selective synthesis of these compounds exists. Herein, a synthetically simple general one-step protocol was developed for the synthesis of a broad range of unsymmetrical dithioacetals consisting of one aromatic and one aliphatic thiol moiety from the corresponding aldehyde/thiol mixture. The mixed S,S-acetals were obtained in high yields, and a great variety of functional groups was tolerated. Kinetic control enabled an excellent selectivity in regard to the unsymmetrical dithioacetal.

Abstract
A series of (t)Bu-substituted Z-oligodiacetylenes (Z-ODAs) are synthesized from the reactions of allenyl/propargylic zinc reagents, obtained from the corresponding propargylic dithiolanes and BuLi, with dithiolane-substituted propargylic aldehydes followed by stereospecific elimination of β-thioalkoxy alcohols under Mitsunobu conditions. The stereochemical assignments are based on NOE experiments. The X-ray structure of the hexamer further supports the Z configuration for each of the double bonds in these ODAs. The photophysical properties of these Z-ODAs have been examined and are compared with known related E- and Z-ODAs with different substituents.
