ABSTRACT:
Methods are provided for carrying out nucleophilic addition reactions using oxo, sulfido or amido complexes of transition metals as reaction catalysts. Exemplary catalysts are oxo complexes of Group 7 transition metals, with rhenium (V) oxo complexes, including dioxo complexes, preferred. Nucleophilic addition reactions that can be catalyzed using the present methods include silylation, hydrosilylation, hydroamination, silylmetalation, carbometalation, aldol reactions, hydro- and carbometalation initiated cyclization/polymerization, and epoxide/aziridine opening. The invention also pertains to novel transition metal complexes that have utility in catalyzing such reactions.
