Abstract

Abstract Studies of the reactions between group 4 metal chlorides (M= Ti, Zr, Hf) and methyllithium at–78 C in toluene can lead to methylidene–metal complexes, H 2 C= MCl 2, by a sequence of monomethylation, α-carbon lithiation and α, μ-elimination of LiCl. Here study of the preparation of alkylidene derivatives of iron was attempted by the interaction of FeCl 3 with n-butyllithium in various ratios at–78 C. The presence of any resulting ...
