权利人:GOVERNING COUNCIL UNIV TORONTO
摘要:There is provided an iron-based complex of formula (IA) or (IB) or a solvate thereof (IA) (IB). The iron-based complex can be used for catalyzing a hydrosillation reaction, such as the hydrosilylation of a ketone or an aldehyde. Also provided is a method for preparing a silyl ether from a ketone or an aldehyde comprising the hydrosilylation of the ketone or aldehyde in the presence of the iron-based complex. Another method is provided for the synthesis of an alcohol from a ketone or an aldehyde comprising the hydrosilylation of the ketone or aldehyde in the presence of the iron-based complex to form a silyl ether, and then hydrolyzing the silyl ether to obtain the alcohol. A process for preparing the iron-based complex is further disclosed.
