results from the insertion of an arene ring into an M-H bond, which has been proposed as the first step in catalytic arene hydrogenations. This insertion is reversible, such that 3 behaves as a "masked hydride" in its reaction chemistry.

氟甲磺酸甲酯配合物 (2,6-Mes2C6H3N=)(2,6-Mes2C6H3NH)TaMe(OSO2CF3) 与 H2 完全反应生成 eta5-环
己二烯基配合物 3。因此配合物 3 是由
芳烃环插入
MH 产生的键,这已被提议作为催化
芳烃氢化的第一步。这种插入是可逆的,因此 3 在其
化学反应中表现为“掩蔽
氢化物”。
