A silylation of vinyliodonium salts using zinc-based silicon reagents as nucleophiles is reported. This cross-coupling is catalyzed by copper, and vinylsilanes are obtained in high yield likely following a Cu(I)/Cu(III) reaction mechanism. The procedure is operationally simple, neither air- nor moisture-sensitive, and tolerant of a range of functional groups. The new method is an addition to the still

chemo-, regio-, and stereoselectiveelectrophilicfluorodesilylation of α-silyl-substituted allylboronate esters. α-Silyl-substituted allylboronate esters can be chemoselectively coupled with Selectfluor, resulting in a variety of (E)-boryl-substituted allyl fluorides in good yields with γ- and (E)-selectivities. The utilities of the obtained (E)-boryl-substituted allyl fluorides are highlighted by
在此,我们报告了 α-甲硅烷基取代的烯丙基硼酸酯的无过渡金属的化学、区域和立体选择性亲电氟代脱甲硅烷基化反应。α-甲硅烷基取代的烯丙基硼酸酯可以化学选择性地与 Selectfluor 偶联,从而以良好的收率生成各种 ( E )-硼基取代的烯丙基氟化物,并具有 γ- 和 ( E )- 选择性。所获得的 ( E )-硼基取代的烯丙基氟化物的效用通过进一步修饰以提供烯丙基或烷基氟化物衍生物而得到强调。
