TRIPHENYLGERMYL-SUBSTITUTED FERROCENES, NEW SYNTHESES OF FERROCENYL LITHIUM AND GRIGNARD REAGENTS
Abstract
Treatment of the disodioferrocene with magnesium bromide in ether represents a new route to the ferrocene di-Grignard reagent; addition of triphenylbromogermane to the di-Grignard solution resulted in almost none of the disubstituted product, but a 32% yield of triphenylgermylferrocene was realized. A new preparation of ferrocenyllithium and 1,1'-ferrocenylenedilithium by the transmetalation reaction occurring between ethyllithium and the corresponding chloromercuriferrocenes in ether is described. The reaction of 1,1'- ferrocenylenedilithium with trimethylchlorosilane produced significant amounts of the monosubstituted product in addition to 1,1'-bis (trimethylsilyl) ferrocene. The preparation of 1,1'-bis(triphenylgermyl)titanocene dichloride, triphenylgermylmanganese pentacarbonyl and triphenylgermyl-pi- cyclopentadienyliron dicarbonyl is described.
