Fe(II) hydride and silyl species of the type [Fe(X)(L)(CyPNP)] (X = H or SiR3; L = N2and/or PMe2Ph;CyPNP = anion of 2,5-bis(dicylcohexylphosphinomethyl)pyrrole) serve as active catalysts for the hydrosilylation of aldehydes and ketones under mild conditions. The catalytic and stoichiometric reactivity of these complexes has been scrutinized in detail and found to support disparate pathways for hydrosilylation of aldehydes involving both a canonical Chalk–Harrod process and a peripheral pathway, which depends upon both precatalyst and substrate selection. Hydrosilylation of ketones, by contrast, appears to proceed via a common mechanism involving an iron silyl species and a peripheral pathway. The unique mechanistic framework for iron-catalyzed hydrosilylation arising from these studies stands in contrast to most previously proposed mechanisms, which feature exclusive carbonyl insertion into a Fe–H bond.
