用溴化烯丙基在自由基反应条件下研究了烷烃的C(sp3) -H烯丙基化反应。在许多情况下,甲基C-H烯丙基化先于亚甲基和甲基C-H烯丙基化,具有完全或高度的位点选择性。烯丙基化合物(如烯丙苯)的C-H烯丙基化反应生成1,5-二烯,烯丙基自由基的SH2′反应发生在阻碍较少的碳上。
The C(sp3)–H allylation of alkanes is investigated by using allyl bromides under radical reaction conditions. In many cases, methine C–H allylation preceded methylene and methyl C–H allylation with complete or a high degree of site selectivity. The C–H allylation of allylic compounds, such as allylbenzene, gives 1,5-dienes with the SH2′ reactions of the allyl radicals occurring at the less hindered carbon.
