摘要

A novel palladium-catalyzed intermolecular ditrifluoromethoxylation of unactivated alkenes has been developed, using a new electrophilic reagent, Selectfluor~(CN), as a strong oxidant, and AgOCF_(3) as a trifluoromethoxide source. Preliminary mechanistic studies revealed that the reaction was possibly initiated by Pd(IV) species, and an unusual cis -addition of CF_(3)O–Pd(IV) into the double bond leads to the formation of the first C–OCF_(3) bond; in addition, the second C–OCF_(3) bond was produced through reductive elimination at high-valent palladium center.
