cyclooctene). Complex 2 reacted with PMePh2 to give [PhBP3]Ir(PMePh2)H2 (5) and 1,3-cyclooctadiene. The protonation of 5 with [H(OEt2)]B[3,5-C6H3(CF3)2]4} gave the classical hydride complex [PhBP3]Ir(PMePh2)H3}B[3,5-C6H3(CF3)2]4} (6). In addition to the formation of allyl complexes 2 and 3, several C−H activation reactions have been observed; addition of PMe3 to 2 provided the cyclometalated product (4) and

铱(H)(η 3 -C 3 H ^ 5)(3)是由[Li(TMED)] [PhBP 3 ](1)与相应的[(烯烃)2 IrCl] 2络合物反应合成的。这些烯丙基络合物用作二卤化物[PhBP 3 ] IrX 2(10,X = 1;12,X = Cl)的前体。除了这些二卤化物之外,还分离了五配位物质[PhBP 3 ] IrMe 2(16)和[ClB(CH 2 PPh 2)3 ] IrCl 2(13)。将CO加至2或3可得到[PhBP3 ]的Ir(CO)2(7),而h的反应2与2得到[PhBP
