A novel method to synthesize unsymmetrical disubstituted ferrocenes

Abstract

A convenient new method for the preparation of 1′-substituted-1-bromoferrocenes and 1′,1‴-disubstituted-biferrocenes has been developed, which can also be applied to the preparation of unsymmetrical disubstituted ferrocenes, which are potentially useful materials possessing nonlinear optical and liquid crystalline properties.
