Abstract

Tris(quinolin-8-yl)phosphite, P(Oquin)(3), promotes the dehydrogenation of H3N center dot BH3 (AB) and the transfer hydrogenation of azoarenes using ammonia borane (AB) as H-2 source. The metal-free reduction of azoarenes proceeds under mild reaction conditions upon which several diphenylhydrazine derivatives are obtained in high yields. The reactivity of P(Oquin)(3) toward AB was evaluated ...
