Abstract

The reactivity of BiV reagents towards very hindered phenols with tert.-butyl groups at 2 and 6 under basic conditions has been studied. Unexpected phenylation at the 4-position and, in several cases, replacement of a tert.-butyl group by phenyl have been observed. The mechanism of these unexpected reactions has been discussed.
