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
Allyl dithiocarbamate as a new β-acyl vinyl anion equivalent
作者:Toshio Hayashi
DOI:10.1016/s0040-4039(00)97568-3
日期:1990.1
The title compound can function as synthetic equivalents of β-formyl vinyl and β-halomethyl vinyl anions, as shown by the conversion of aldehydes to 4-hydroxy-2(E)-enals and 4-hydroxy-1-iodo-2(E)-alkenes.
A NEW, GENERAL, AND STEREOSELECTIVE SYNTHESIS OF LONG CHAIN TETRAENOIC ACIDS EXAMPLIFIED BY β-PARINARIC ACID

日期:1985.3.5
All trans-9,11,13,15-octadecatetraenoic acid was first synthesized in a stereoselective manner, using pentadienyl and allyl dithiocarbamates as the starting materials. This synthesis confirmed that β-parinaric acid has all trans configurations about the four double bonds.
Regiospecific iodocyclization of S-allyl dithiocarbamates: synthesis of 2-imino-1,3-dithiolane and 2-iminium-1,3-dithiolane derivatives

4-Alkyl-2-imino-1,3-dithiolanes and 4-alkyl-2-iminium-1,3-dithiolanes were prepared in excellent yields with complete regiospecificity under mild conditions by the iodocyclization of S-allyl dithiocarbamates. Dehydrohalogentaion of the 4-alkyl-2-imino-1,3-dithiolanes gave 4-alkylidene-2-imino-1,3-dithiolanes in excellent yields. (C) 2009 Elsevier Ltd. All rights reserved.
