Copper(II)-catalyzed silyl conjugate addition to α,β-unsaturated conjugated compounds: Brønsted base-assisted activation of Si-B bond in water

Org Lett. 2012 Apr 20;14(8):2090-3. doi: 10.1021/ol300618j. Epub 2012 Apr 11.

Abstract

A mild method for the installation of the dimethylphenylsilyl group on the β-carbon of electron-deficient olefins is reported. In the presence of a catalytic amount of copper(II) (1 mol %) and amine base (5 mol %) at rt, the transformation proceeds efficiently in water within 1.5-5 h to afford β-silylated products in yields of up to 90%.
