Synthesis of 1,1′-Bis(1-Methyl/Chloro-2,3,4,5-Tetraphenyl-1-Silacyclopentadienyl) [Ph(4)C(4)Si(Me/Cl)-(Me/Cl)SiC(4)Ph(4)] from Silole Anion [MeSiC(4)Ph(4)](−)•[Li(+) or Na(+)] and Silole Dianion [SiC(4)Ph(4)](2−)•2[Li(+)]; Oxidative Coupling of Silole Anion [MeSiC(4)Ph(4)](−)•[Li(+) or Na(+)] by Ferrous Chloride (FeCl(2)) and Oxidative Coupling and Chlorination of Silole Dianion [SiC(4)Ph(4)](2−)•2[Li(+)] by Cupric Chloride (CuCl(2))

A reaction of silole anion {[MeSiC(4)Ph(4)](−)•[Li(+) or Na(+)] (1) with anhydrous ferrous chloride (FeCl(2)) in THF (tetrahydrofuran) gives 1,1′-bis(1-methyl-2,3,4,5-tetraphenyl-1-silacyclopentadienyl) [Ph(4)C(4)Si(Me)-(Me)SiC(4)Ph(4)] (2) with precipitation of iron metal in high yield. Silole dian...
