o-(α-Benzotriazolylalkyl)phenols: Novel Precursors for the Preparation of 1,1-Bis(2-hydroxyaryl)alkanes
Reactions of o-(α-benzotriazolylalkyl)phenols with a variety of substituted phenols and naphthols in the presence of a base provide efficient access to symmetrical and more importantly to unsymmetrical 1,1-bis(2-hydroxyaryl)alkanes.

Kinetics of the Bromination of Phenols and Oligonuclear Phenolic Compounds, 4. The Influence of the Neighboring Phenolic Unit on the Reactivity of Dihydroxydiphenylmethanes
The bromination of 15 dinuclear phenolic compounds (dihydroxydiphenylmethanes, methylene bisphenols) by molecular bromine in acetic acid was studied kinetically at 22 deg C.In all compounds the electrophilic substitution occurred in ortho-position to the
