Base-Promoted Synthesis of O-Aryl/Alkyl N,N-Dimethylthiocarbamates Starting from Inexpensive and Environmentally Benign Disulfide

Abstract

A series of O-aryl (alkyl) N,N-dimethylthiocarbamates were synthesized in good yields (70–77%) by reacting substituted phenols or alkyl alcohol with inexpensive, stable, and environmentally benign tetramethylthiuram disulfide (TMTD) in the presence of NaH. By avoiding use of the toxic and corrosive N,N-dialkylthiocarbamoyl chloride, the method provides a green and facile preparation for some important precursors of potentially biologically reactive compounds.
