Borane tert-butylamine is an amine borane complex derived from tert-butylamine and borane. It is a colorless solid.

The compound is prepared by the reaction of tert-butylammonium chloride and sodium borohydride:^[2]

t-BuNH₃Cl + NaBH₄ → t-BuNH₂BH₃ + H₂ + NaCl

In organic synthesis, borane tert-butylamine can be used for selective reduction of certain functional groups including aldehydes, ketones, oximes, and imines.^[3]

In photographic processing, it is used in the E-4 process, as "chemical enlighting" step in the processing of the film.
