Inter- and intramolecular addition of the boron-cyanide bond of cyanoboranes across a carbon–carbon double bond of allenes proceeded in the presence of palladium catalysts, affording allylboranes that bear a cyano group at the β-position regioselectively.
在钯催化剂的存在下,氰基硼烷的硼-氰化物键跨烯丙基的碳-碳双键进行分子间和分子内加成,从而提供了在β位置区域上具有氰基的烯丙基硼烷。
