Primary amides to amines or nitriles: a dual role by a single catalyst

Autor: Kartick Dey, Jasimuddin Ahmed, Hari Sankar Das, Arpan Das, Shyamal Das, Bhagat Singh, Rahul Koottanil Haridasan, Swadhin K. Mandal

Publikováno v: Chemical communications (Cambridge, England). 55(79)

We report a manganese-catalyzed hydrosilylative reduction of various primary amides to amines (25 examples). On simple modification of the reaction conditions such as in the presence of a catalytic amount of secondary amide, the same catalyst can tra
