Organic synthesis

Highly selective reducing agent for aldehydes, ketones, oximes, enamines. Especially useful for reductive amination of ketones and aldehydes, reductive alkylation of amines and hydrazines, reductive displacement of halides & tosylates, and deoxygenation of aldehydes & ketones.

Reductive methylation of protein amino groups (Sanders et al, Biochem. J. (1982) 203, 331-334)
