Abstract
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 hydrides proceeds by formation of a 1: 1 adduct and subsequent hydrogenolysis of the tin‐nitrogen bond of the adduct.
