A palladium-catalyzed highly selective tetrafunctionalization of 3,6-I2-o-carborane and 4,7-I2-o-carborane has been developed, leading to the preparation of 3,6-dialkenyl-4,11-R2-o-carboranes and 4,7-dialkenyl-5,11-R2-o-carboranes (R = alkyl, allyl and aryl) in moderate to excellent yields. This represents a new strategy for selective synthesis of polyfunctionalized o-carborane derivatives via a one-pot process.
发展了钯催化的 3,6-I2-o-卡硼烷和 4,7-I2-o-卡硼烷的高选择性四官能化反应，通过一锅法以中等至优秀的收率制备了 3,6-二烯基-4,11-R2-o-卡硼烷和 4,7-二烯基-5,11-R2-o-卡硼烷（R = 烷基、烯丙基和芳基）。这代表了通过一锅法选择性合成多官能化 o-卡硼烷衍生物的新策略。
