摘要：

The iridium complex Cp*(PMe3)Ir(Me)(SiMe2-OTf) (2) reacts with LiB(C6F5)(4)(Et2O)(2) to form a mixture of the silene complex [Cp*(PMe3)Ir(eta (2)-CH2SiMe2)(H)]-[B(C6F5)(4)] (3) and the base-stabilized silylene complex [Cp*(PMe3)(Me) (SiMe2(Et2O)][B(C6F5)](4)] (4). The silene complex 3 has been crystallographically characterized. Addition of pyridine to this mixture affords Cp*(PMe3)-Ir(Me)(SiMe2(L)][B(C6F5)(4)] (5a, L = pyridine) in good yield, whereas addition of CO or ethylene results in clean formation of CP*(PMe3)Ir(L) (SiMe3)][B(C6F5)(4]) (8a, L = CO; 8b, L = C2H4).
