[Structure: see text] A highlyefficient and simple synthesis of dithiocarbamates is possible based on the one-pot reaction of amines, CS2, and alkyl halides without using a catalyst under solvent-free conditions. The mild reaction conditions, high yields, and broad scope of the reaction illustrate the good synthetic utility of this method. The reaction is a highly atom-economic process for production

solvent freesynthesis of S-benzylic dithiocarbamate esters has been demonstrated via the iodine mediated direct C-S coupling of benzylic alcohols with dithiocarbamate anions generated in-situ by the reactions of amines and carbon disulphide. All the reactions were very fast (15–30 min) and performed under open air atmosphere. Cyclic and acyclic secondary amines, primary amine, aromatic amine actively
A new strategy for the synthesis of a variety of dithiocarbamates and thioamides has been developed employing inexpensive and readily available methylarenes under metal-free and solvent-free conditions. The approach offers a one-pot procedure and has also been extended to the synthesis of a diverse range of benzyl esters. (C) 2014 Elsevier Ltd. All rights reserved.

The presence of cesium carbonate and tetrabutylammonium iodide (TBAI) facilitated efficient thiocarbonylation of alcohols, and thiocarbamation of amines, using carbon disulfide with alkyl halides. This protocol was mild, chemoselective, and efficient, compared to the existing methods. (C) 2001 Published by Elsevier Science Ltd.
