of δ‐substituted para‐quinone methides has been described. Under mild conditions, diarylmethanes bearing CF3‐ and CN‐substituted all‐carbon quaternary stereocenters and diarylmalononitriles were obtained in excellent yields. The process displays a broad substrate scope and the products can be successfully transformed to a series of all‐carbon quaternary centres that may serve in the synthesis of valuable

A cross-electrophile coupling reaction of gem-difluoroalkenyl tosylate with α-CF3 benzyl tosylate is presented. This protocol is the first example of cross-electrophile coupling between twodifferent tosylates by Pd/Ni cooperative catalysis.
