摘要

2, 6-Di-t-butylphenol and its 4-substituted derivatives (1) have been shown to undergo novel photochemical transposition to isomeric phenols 2 and 3, being accompanied by de-t- butylation to give 4. Involvement of the triplet excited state of 1 was confirmed by sensitization and quenching experiments. Evidence is presented for the initial tautomerization of 1 to the ketonic tautomers which undergo further photochemical ...
