The iridium complex Cp*(PMe3)Ir(Me)(SiMe2OTf) (2) reacts with LiB(C6F5)4(Et2O)2 to form a mixture of the silene complex [Cp*(PMe3)Ir(η2-CH2SiMe2)(H)][B(C6F5)4] (3) and the base-stabilized silylene complex [Cp*(PMe3)Ir(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
铱配合物Cp *(PMe 3)Ir(Me)(SiMe 2 OTf)(2)与LiB(C 6 F 5)4(Et 2 O)2反应形成
硅配合物[Cp *(PMe 3)。IR(η 2 -CH 2森达2)(H)] [B(C 6 ˚F 5)4 ](3)和碱稳定的亚甲
硅烷复合的[Cp *(PME 3)IR(ME)(森达2(Et 2 O))] [B(C 6 F 5)4 ](4)。
硅配合物3已经在晶体学上进行了表征。向该混合物中添加
吡啶可得到高收率的Cp *(PMe 3)Ir(Me)(SiMe 2(L)] [B(C 6 F 5)4 ](5a,L =
吡啶),而添加CO或
乙烯导致干净形成Cp *(PMe 3)Ir(L)(SiMe 3)] [B(C 6 F 5)4 ](8a,L = CO;8b,L = C 2 H 4)。
