The palladium-catalyzed regioselective allylation reaction between chloromethyl(hetero)arenes and allyl pinacolborate is reported in this work. Chloromethylarenes smoothly reacted with allyl pinacolborate, producing para-allylated dearomatization products or para-allylated arenes in satisfactory to good yields. 2-(Chloromethyl)thiophenes and 2-(chloromethyl)furans bearing substituents on the 5-positions
在这项工作中报道了氯甲基(杂)芳烃与频哪醇硼酸烯丙酯之间的钯催化的区域选择性烯丙基化反应。氯甲基芳烃与频哪醇硼酸烯丙基酯平稳反应,以令人满意的产率获得对芳基化的脱芳烃化产物或对芳基化的芳烃。在5-位带有取代基的2-(氯甲基)噻吩和2-(氯甲基)呋喃也与频哪醇硼酸烯丙酯平滑地反应,以令人满意的产率产生5-烯丙基化的脱芳香化产物。
