摘要：

Amine-borane dehydrogenation: Ruthenium PNP amido pincer complex I catalyzes the dehydrocoupling of dimethylamineborane to cyclic dimer (Me 2NBH2)2. The results are in agreement with a mechanism including initial alternative dehydrogenation to aminoborane Me 2NBH2 versus metalcentered B-N coupling via diborazane Me2HNH2BMe2NBH3. Formation of borametallacycle II, which features a rare four-membered Ru-N-B-H ring, results in considerable slowdown of the catalytic activity. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
