Secondary amine formation from reductive amination of carbonyl compounds promoted by Lewis acid using the InCl3/Et3SiH system.
A robust and reliable method has been developed for reductive amination of primary amines with various aldehydes and ketones using Zn(ClO(4))(2) x 6 H(2)O as a catalyst. [In-H] generated in situ via a combination of InCl(3) and Et(3)SiH is employed as an effective reducing system. A variety of secondary amines can be synthesized in a one-pot procedure in excellent yields.
