Abstract

Abstract Suspensions of zinc or cadmium sulfide powders in a protic solvent catalyse the linear addition of enol ethers and olefins to 1, 2-diaryl-and 1-aryl-2-alkyl-1, 2-diazenes, producing allylhydrazine derivatives. Relative quantum yields decrease sharply when the 1, 2-diazene is more difficult to reduce, while their relationship to the oxidation potential of the enol ether/olefin is complicated. Reduction to 1, 2-diarylhydrazine and concomitant ...
