资源简介：
The dearomatizing spirocyclization of phenolic biarylic ketones using PhI(OCOCF3)2 as oxidant is presented. The reaction affords various cyclohexadienones through C–C bond cleavage under mild conditions. Mechanistic investigations reveal that an exocyclic enol ether acts as the key intermediate in the transformation.
