A convenient new method was developed for the preparation of 1′-substituted-1-bromoferrocenes which are important precursors for the preparation of 1′,1?-disubstituted-biferrocenes. This method can also be applied to prepare asymmetrical disubstituted ferrocenes, which are potentially useful materials possessing non-linear optical and liquid crystalline properties.
