Ar. Katritzky et al., O-(ALPHA-BENZOTRIAZOLYLALKYL)PHENOLS - NOVEL PRECURSORS FOR THE PREPARATION OF 1,1-BIS(2-HYDROXYARYL)ALKANES, Journal of organic chemistry, 59(24), 1994, pp. 7209-7213
Reactions of o-(alpha-benzotriazolylalkyl)phenols with a variety of su
bstituted phenols and naphthols in the presence of a base provide effi
cient access to symmetrical and more importantly to unsymmetrical 1,1-
bis(2-hydroxyaryl)alkanes.
