(Me3P)反应。RhCl与(THF) 3LiSi-(SiMe3) 3产生热不稳定络合物(Me3P) 3RhSiMe2SiMe (SiMe3) 2(1),可能是通过一系列1,2 -和1,3 -迁移。类似的铱反应导致类似的重排,得到i - i环(Me3P) s (H) IrSiMe2SiMe (SiMe3) SiMe2CH2作为非对映体(2a, b)的混合物,氢催化转化为平衡混合物。
Reaction of (Me3P).] RhCl with (THF) 3LiSi-(SiMe3) 3 generates the thermally unstable complex (Me3P) 3RhSiMe2SiMe (SiMe3) 2 (1), probably via a series of 1, 2-and 1, 3-migrations. The analogous iridium reaction results in a similar rearrangement to give the i i iridacycle (Me3P) s (H) IrSiMe2SiMe (SiMe3) SiMe2CH2 as a mixture of diastereomers (2a, b), which is catalytically converted to an equilibrium mixture by hydrogen.
