In this report, nickel-catalyzed hydroboration of vinylarenes and aliphatic alkenes is investigated. The non-innocent phenalenyl ligand moiety in the nickel complex Ni(PLY)2(THF)2 (1) was utilized as an electron reservoir for the selective hydroboration reaction in the presence of pinacolborane under ambient conditions. The mechanistic investigations revealed that the alkene hydroboration reaction takes place through a single electron transfer (SET) from the phenalenyl ligand backbone leading to the cleavage of the B-H bond.
在本报告中，研究了镍催化的乙烯基芳烃和脂肪族烯烃的硼氢化反应。镍配合物Ni(PLY)₂(THF)₂ (1)中具有非惰性的苊烯基配体部分被用作电子库，用于在环境条件下频哪醇硼烷存在时的选择性硼氢化反应。机理研究表明，烯烃硼氢化反应通过从苊烯基配体主链进行的单电子转移(SET)发生，导致B-H键的断裂。
