undergo carbon–carbon bond formation followed by carbon–sulphurbondcleavage in the presence of zeolite catalysts to give 1-substituted amino-1-methylthio-2-nitroethenes. This carbon-sulphurbondcleavage is facilitated by the presence of rare earth cations in the zeolite-Y framework. The shape selectivity of the zeolite also plays an important role in this cleavagereaction. Force field calculations

Dimethyl carbonimidodithioates derived from various primary amines and amino acid esters (1) can be converted to S-methyl thiolcarbamates (2) by H-mordenite or H-Y zeolite catalysis in moderate to good yields.
