摘要

In the case of isothiocyanates the sole isolable products were the P-thioamido sulfoxides (Table I, type C). Apparently, because of the lesser electronegativity of sulfur as compared to oxygen, the methylene group of the primary product is insufficiently acidic to undergo reaction with a second mole of the isothiocyanate. The opposite effect was observed during the reaction of phenyl isocyanate with the anion of dimethyl sulfone.
