Conversion of thiocarbamates to carbamates
Tetrahedron, 1993Abstract Treatment of methyl N-methylthionocarbamate (2a) with a catalytic amount of iodine or conc. H2SO4 results in the unexpected formation of the isomer, methyl N-methylthiolcarbamate (3a) in 90% yield. This has subsequently been transformed into methyl N-methylcarbamate (4a), by sodium methoxide.

Thiocarbamate Sulfoxides: Potent, Selective, and Biodegradable Herbicides
Science, 1974Sulfoxidation of thiocarbamates yields a new class of chemicals having increased herbicidal activity along with greater tolerance of corn and soybeans in greenhouse tests. However, their thermal stability is not favorable. These sulfoxides are intermediates in the mammalian metabolism of thiocarbamates, being formed by liver microsomal oxidases and ...

Thermal rearrangement of O-methyleneamino thiocarbamates
Journal of the Chemical Society, Perkin Transactions 2, 1974The rate of the thermal, uncatalysed, [1,3] rearrangement of aromatic O-methyleneamino thiocarbamates to S-methyleneamino thiocarbamates in solution is insensitive to changes in both solvent polarity and substituent on ring and imino-carbon atoms, suggesting a transition state involving little charge separation.
