economic, and green method for the synthesis of dithiocarbamate derivatives in water. The one-pot, three-component condensation of primary and secondary amines with carbon disulfide and unsaturated carbonyl compounds or alkyl halides under ultrasonic irradiation was developed as a green and fast protocol for the rapid high-yielding preparation of dithiocarbamates in water.

[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
Cyclic ammonium salts of dithiocarbamic acid: stable alternative reagents for the synthesis of <i>S</i>-alkyl carbodithioates from organyl thiocyanates in water
conditions. Here, we report an efficient and practical method for the preparation of libraries of carbodithioate esters from organyl thiocyanates by reacting with cyclic amine-based dithiocarbamic acid salts in water. The protocol is found to be applicable in general to various thiocyanates such as benzyl/aroyl methyl/cinnamyl and so on. Other notable features include no by-products such as disulfides, metal-

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
