triethylsilane and I2. This system offers high regio- and stereoselectivity to afford (E)-vinyl iodides in good yields under mild conditions. Furthermore, the hydroiodination reaction shows high functional group tolerance toward alkyl, methoxy, halogen, trifluoromethyl, cyano, ester, halomethyl, acid-sensitive silyl ether, and acetal moieties.
在本文中,我们报道了使用HI内炔的有效且实用的碘氢化生成易地从容易获得的三乙基硅烷和我2。该系统具有高区域选择性和立体选择性,可在温和条件下以良好的收率提供 ( E )-乙烯基碘化物。此外,氢碘化反应显示出对烷基、甲氧基、卤素、三氟甲基、氰基、酯、卤代甲基、酸敏感性甲硅烷基醚和缩醛部分的高官能团耐受性。
