A novel palladium-catalyzed intermolecular ditrifluoromethoxylation of unactivated alkenes has been developed, using a new electrophilic reagent, SelectfluorCN, as a strong oxidant, and AgOCF3 as a trifluoromethoxide source. Preliminary mechanistic studies revealed that the reaction was possibly initiated by Pd(IV) species, and an unusual cis-addition of CF3O-Pd(IV) into the double bond leads to the formation of the first C-OCF3 bond; in addition, the second C-OCF3 bond was produced through reductive elimination at high-valent palladium center.

未活化烯烃的钯催化分子间二三氟甲氧基化：由 Pd(IV) 引发的 CF3O-钯化

使用新型亲电试剂 SelectfluorCN 作为强氧化剂，AgOCF3 作为三氟甲醇盐来源，开发了一种新型钯催化的未活化烯烃的分子间二三氟甲氧基化。初步的机理研究表明，该反应可能是由 Pd(IV) 物种引发的，CF3O-Pd(IV) 不寻常的顺式加成双键导致形成第一个 C-OCF3 键；此外，第二个 C-OCF3 键是通过高价钯中心的还原消除产生的。
