The Parent Cyclopentadienyltin Cation,Its Toluene Adduct,and the Quadruple‐Decker [Sn3Cp4]2+ |
| |
| Abstract: | Truly cationic metallocenes with the parent cyclopentadienyl ligand are so far unknown for the Group 14 elements. Herein we report on an almost “naked” SnCp]+ cation with the weakly coordinating Al{OC(CF3)3}4]? and {(F3C)3CO}3Al?F?Al{OC(CF3)3}3]? anions. SnCp]Al{OC(CF3)3}4] was used to prepare the first main‐group quadruple‐decker cation Sn3Cp4]2+ again as the Al{OC(CF3)3}4]? salt. Additionally, the toluene adduct CpSn(C7H8)]Al{OC(CF3)3}4] was obtained. |
