Ruthenium(IV) complexes were identified as key intermediates of C−H/O−H activations by weak O‐coordination. Thus, the annulations of sulfoxonium ylides by benzoic acids provided expedient access to diversely‐decorated isocoumarins with ample scope. Detailed experimental and computational studies provided strong support for a facile BIES‐C−H activation, along with cyclometalated ruthenium(IV) intermediates within a versatile ruthenium(II/IV) catalysis regime (BIES=base‐assisted internal electrophilic substitution).

钌（IV）通过弱O配位参与CH活化/环化

钌（IV）配合物通过弱O配位被确定为CHH / OH活化的关键中间体。因此，苯甲酸对亚砜基的环化反应可以方便地获得种类繁多，范围广的异香豆素。详细的实验和计算研究为灵活的BIES-C-H活化以及多功能钌（II / IV）催化方案中的环金属化钌（IV）中间体（BIES =碱辅助内部亲电取代）提供了有力的支持。
