摘要

The 1, 4 hydrosilation of a variety of simple α, β-unsaturated enones as catalyzed by B (C6F5) 3 (1–2%) is described. For substrates with no steric hindrance near the β-carbon, 1, 4 addition of silane is very clean; in other instances, 1, 2 hydrosilation is competitive. The reaction is facile with five commercially available silane reagents. For two examples, a novel hydrosilation of the resulting silylenol ethers was also observed. The net trans ...
