Synthesis and Reactivity of Heterobimetallic Co-PAlP Pincer Complexes

A cobalt complex ligated with a PAlP pincer ligand was synthesized. The Lewis acidity of the aluminum atom on the cobalt complex was confirmed by coordination with 4-dimethylaminopyridine (DMAP). Reactions of the cobalt complex with H2O, EtOH, i-PrOH, and t-BuOH efficiently afforded the corresponding cobalt hydride complexes.
