[摘要]:A convenient method for the efficient and regioselective monofluorination of allyl silanes to afford 1-fluoro-3-silyl-2-ols in 43-62% yields via fluorohydroxylation, using Selectfluor as the eletrophilic fluorination reagent has been developed. The regioselectivity can be rationalized by considering the stabilization of the beta-carbocation intermediate by the silyl group. |
