Synthesis of N-and N,N-dialkyl-S-alkylthiolcarbamates by the rearrangement of N-and N,N-dialkyl-O-thioncarbamates

Abstract

A series of N- and N,N-dialkyl-S-alkylthiolcarbamates were synthesized by the rearrangement of N- and N,N-dialkyl-O-alkylthioncarbamates in the presence of diethyl sulfate. The synthesis of some compounds without catalyst was also performed. The compounds were identified by IR, 1H NMR and MS spectroscopic methods. The starting thioncabamates were obtained from the corresponding xanthogenacetates and amines and their structures were also confirmed by IR, 1H NMR and MS data. Some of the thiolcarbamates were characterized for the first time in the literature.
