Mechanistic aspects of transition metal-catalyzed hydrogen transfer reactions

Joseph S. M. Samec, Jan-E. Bäckvall, Pher G. Andersson and Peter Brandt


In this tutorial review recent mechanistic studies on transition metal-catalyzed hydrogen transfer reactions are discussed. A common feature of these reactions is that they involve metal hydrides, which may be monohydrides or dihydrides. An important question is whether the substrate coordinates to the metal (inner-sphere hydrogen transfer) or if there is a direct concerted transfer of hydrogen from the metal to substrate (outer-sphere hydrogen transfer). Both experimental and theoretical studies are reviewed.
