The mechanism of the addition of organotin mono-hydrides across the C=N bond of isocyanates and the C=S bond of isothiocyanates has been studied more closely. A polar mechanism is operative in both types of additions as appeared from the lack of acti

Triorganotin hydrides readily add across the nitrogen-nitrogen double bond of azobenzene and diethyl azodicarboxylate to produce organotin-substituted hydrazine derivatives. The reduction of these azo compounds and of aryl isocyanates by triorganotin
