Abstract

Dehydrogenation of amine boranes is catalyzed efficiently by the iridium pincer complex (κ3-1,3-(OPtBu2) 2C6H3)Ir(H)2 (1). With CH 3NH2BH3 (MeAB) and with AB/MeAB mixtures (AB = NH3BH3), the rapid release of 1 equiv of H2 is observed to yield soluble oligomeric products at rates similar to those previously reported for the dehydrogenation of AB catalyzed by 1. ΔH for the dehydrogenation of AB, MeAB, and AB/MeAB mixtures has been determined by calorimetry. The experimental heats of reaction are compared to results from computational studies.
