Silanes are useful intermediate functional groups because they can be used in a wide range of transformations and exhibit high functional group compatibility. Current methods for the hydrosilylation of stryrenes and alkynes typically rely on expensive catalysts such as platinum. Copper-catalyzed silylations of C—C π-bonds is currently limited to highly reactive π-bonds such as alkynes and allenes. The purpose of this research is to silylate styrene and alkyne derivatives with a copper catalyst and a disilane as the silicon source. These methods should be cost effective and the organosilane products can be used as substrates in other reactions. Various ligands with copper were used to optimize the reaction and methanol was added as a proton source. Future work will include exploration of other ligands that could produce the organosilanes.
