A simple, mild, catalyst-free, and efficacious KOtBu-mediated reductive cyanation reaction of tertiary amides provides a series of α-aminonitriles in good yields under hydrosilylation conditions with good functional group tolerance. The reaction works well with readily available amide substrates, cheap KOtBu, and a commercially available hydrosilane (EtO)3SiH and the workup is convenient.
