Treatment of α-silyl-α,β-unsaturated enones, readily preparable as regio- and stereodefined compounds in high yields, with either 2 equiv. of ICl or one equiv. each of ICl and AlCl3 provides the corresponding α-iodo-α,β-unsaturated enones in high yields.
处理α-甲硅烷基-α,β-不饱和烯酮,可以容易地制备为区域和立体定义的化合物,收率较高,为2当量。ICl或一个当量。ICl和AlCl 3各自以高收率提供相应的α-碘-α,β-不饱和烯酮。
