Abstract
The reaction of α-haloketones with a variety of dithiocarbamate derivatives for the synthesis of various 2-alkylthiothiazole heterocyclic compounds was investigated in this thesis. To this end, different dithiocarbamates were initially synthesized through the reaction of amines, carbon disulfide and various alkyl halides; then, these dithiocarbamates were reacted with α-bromoketones (bromoacetophenone and chloroacetone) resulting in the formation of range of 2-alkyl thiothiazoles. To optimize the reaction conditions, ethanol and water were tested as solvents in the presence of ZrCl4 as catalyst. According to the data obtained, ethanol was selected as the optimum solvent using ZrCl4 as...
Synthesis of Dithiocarbamate Derivatives and Their Applications to Prepare Heterocyclic Compounds
, M.Sc. Thesis Sharif University of Technology ; Saeedi, Mohammad Reza (Supervisor)
Abstract
Sulfur containing compounds are known as the most applicable group of organic compounds. Due to their medicinal and biological applications, dithiocarbamates are the most considerable among the many sulfur containing compounds. There are many procedures reported to synthesize these compounds as synthetic intermediates instead of thiophosgen and isothiocyanates. The reaction of amine and carbon disulfide is reported as the best and least hazardous way to synthesize this functional group. In this project heterocyclic compounds such as thiazoles, thiazolidine-2-thione, and 2-(alkylthio)thiazol-4(5H)-one derivatives were synthesized from the reaction of prepared dithiocarbamates with in situ...
