Abstract

From the results of bromination of 4-hydroxybiphenyl, its esters, methyl ether, and their halo derivatives, it is evident that the 3-, 5-and 4 '-positions of the biphenyl nucleus are the ones activated. According to well-known theory, electrophilic attacks of bromine are facilitated by relatively high electron densities in these three positions. The solvent plays an important role in orientation of an entering substituent into these positions as is evident in the cases of ...
