Cationic (2a,b) and formally zwitterionic (3a,b) Rh(I) and Ir(I) complexes supported by P,N-substituted indene or indenide ligands (respectively) have been employed in the selective hydroboration of substituted vinylarenes with pinacolborane (HBpin, pin = 1,2-O2C2Me4). Notably, 3a,b exhibited remarkably high, but differing, selectivities in the hydroboration of 1-phenylpropene.
分别由P,N-取代的茚或茚配体负载的阳离子(2a,b)和正式的两性离子(3a,b)Rh(I)和Ir(I)配合物已用于频哪醇硼烷的选择性乙烯基芳烃的选择性硼氢化反应中(HBpin,pin = 1,2-O 2 C 2 Me 4)。值得注意的是,3a,b在1-苯基丙烯的硼氢化中表现出显着高的选择性,但是不同。
