Nitrile sulphides
Abstract
Kinetic studies provide support for benzonitrile sulphide as an intermediate produced in the decarboxylation of 5-phenyl-1,3,4-oxathiazol-2-one; thermolysis of 5-methyl-1,3,4-oxathiazol-2-one in the presence of dimethyl acetylenedicarboxylate produced dimethyl 3-methylisothiazole-4,5-dicarboxylate, presumably via acetonitrile sulphide.
