摘要

Several chlorophenoxy phenols were converted to their triflates by reaction with trifluoromethanesulfonyl chloride. The trifilates undergo triplet seneltlzed photolytic cyclizations at 300 nm in acetone to give chlorodibenzofurans or singlet state substitution reactions in carbon tetrachloride saturated with chlorine gas to give the corresponding chlorine substituted diphenyl ethers. 2-Chloro-3-hydroxy dlbenzofuran was similarly ...
