    <description descriptionType="Abstract">In this paper we examined the catalytic activity of in situ prepared bidentate azolium salt/[RhCl(COD)](2) catalyst system in the transfer hydrogenation of imines with i-propanol to the corresponding amine. The first in situ transfer hydrogenation of imines to amines is described using [RhCl(COD)](2) with bidentate azolium ligands. New bidentate azolium salts (1a-c, 2a-c) as NHC precursors have been synthesized and characterized. The in situ prepared three-component bidentate azolium salts (LHX)/[RhCl(COD)](2) and t-BuOK catalyzes quantitatively the transfer hydrogenation of imines under mild reaction conditions in i-propanol. The results show that bidentate benzimidazolium salts were observed to be more active in reducing imines. Moreover, the method is simple and effective against various imines. (C) 2020 Elsevier B.V.
