Abstract

The new alane/bis(phosphine) PAlP pincer-type ligands 2-Me and 2-Et have been prepared by protolysis reactions of N-(diisopropylphoshino)acetamide with Me₃Al or Et₃Al in a 2:1 ratio. Upon reaction with a "RhCl" source and pyridine, 2-Me gave rise to a (PAlP)RhMe(py) compound (4-Me), while 2-Et led to the analogous hydride complex (PAlP)RhH(py) (4-H), with a migration of the chloride from Rh to Al. 4-Me and 4-H possess the shortest Rh-Al bonds to date.
