Abstract:
The systhesis of ferrocenyllithium was undertaken by the transmetalation reaction using ferrocenylmercuric chloride I as the starting material. The reacion of I with phenyllithium in ether solution, followed by carbonation gave ferrocenecarboxylic acid and benzoic acd. Similar results were obtained in ether-tetrahydrofuran mixtures. The transmetalation went practically to completion when ethyllithium was used in place of phenyllithium. In another experiment, I and ethyllithium 12.5 mol-ratio were mixed, and solid triphenylchlorosilane was added after 1 hr. Ferrocenyltriphenylsilane was isolated in 66 yield as well as ferrocene in 8 yield. Evidence of some dilithiated product was found when the I-ethyllithium reaction mixture was treated with benzophenone.
