Deoxygenative hydroboration of primary, secondary, and tertiary amides: Catalyst‐free synthesis of various substituted amines

Abstract Transformation of relatively less reactive functional groups under catalyst‐free conditions is an interesting aspect and requires a typical protocol. Herein, we report the synthesis of various primary, secondary, and tertiary amines through hydroboration of amides using pinacolborane under catalyst‐free and solvent‐free conditions. The deoxygenative hydroboration of primary and secondary amides proceeded with excellent conversions. The comparatively less reactive tertiary amides were also converted to the corresponding N , N ‐diamines in moderate yields under catalyst‐free conditions, although alcohols were obtained as a minor product.
