Methylbenz[e]indenyl asymmetric ansa-metallocene and silylamido zirconium complexes

2-(2-Methylbenz[e]indenyl)-2-cyclopentadienyl-propane [MeC13H8CMe2C5H5] (1) (MBICMe2Cp), was synthesized by reaction of LiMBI with 6,6-dimethylfulvene. The silyl derivatives [MeC13H8SiMeRCl] (R=Me 2, H 4) were isolated by reaction of 2-methylbenz[e]indene (LiMBI) with SiMeRCl2 and further react...

The silyl derivatives [MeC13H8SiMeRCl] (R=Me 2, H 4) were isolated by reaction of 2-methylbenz[e]indene (LiMBI) with SiMeRCl2 and further reactions of 2 and 4 with NaCp afforded the silyl-bridged compounds [MeC13H8SiMeRC5H5] (R=Me 3, H 5).
