A copper-catalyzed silylation of propargyl dichlorides was developed to access chloro-substituted allenylsilanes under mild reaction conditions. Moreover, enantioenriched chloro-substituted allenylsilanes can be synthesized in moderate to high yields and good enantioselectivities with this protocol.
开发了铜催化的炔丙基二氯化物的甲硅烷基化反应,以在温和的反应条件下获得氯取代的烯丙基硅烷。而且,利用该方案可以以中等至高收率和良好的对映选择性合成富含对映体的氯取代的烯丙基硅烷。
