Hydrosilylation BINAP-copper

Copper-based asymmetric hydrosilylation of aryl/alkyl ketones can also be achieved in up to 92% ee using 1 mol% CuF in the presence of BINAP and PhSiHs. In contrast to the method developed by Lipshutz, this process does not require the use of anaerobic reaction conditions and is actually enhanced when performed under oxygen.
