Ty. Dong et Ll. Lai, A NOVEL METHOD TO SYNTHESIZE ASYMMETRICAL DISUBSTITUTED FERROCENES, Journal of organometallic chemistry, 509(2), 1996, pp. 131-134
A convenient new method was developed for the preparation of 1'-substi
tuted-1-bromoferrocenes which are important precursors for the prepara
tion of 1', 1triple prime-disubstituted-biferrocenes. This method can
also be applied to prepare asymmetrical disubstituted ferrocenes, whic
h are potentially useful materials possessing non-linear optical and l
iquid crystalline properties.
