Solutions of n-butyllithium and N, N, N′, N′-tetramethylethylenediamine (TMEDA) readily dilithiate ferrocene in high yields. The 1, 1′-dilithioferrocene can be used in situ, or when isolated as the pyrophoric adduct [(C 5 H 4 Li) 2 Fe]· TMEDA, to prepare the following complexes in high yields: ferrocene-1, 1′-bis (dimethylarsine)(Fdma), ferrocene-1, 1′-bis (diphenylarsine)(Fdpa), ferrocene-1, 1′-bis (dimethylphosphine)(Fdmp), ferrocene-1, 1′-bis (diphenylphosphine)(Fdpp). Elemental sulfur reacts with solutions of dilithioferrocene in …
