A challenging catalytic hydroarylation of highly electron deficient styrenes has been developed on the basis of efficient cooperation between a calcium(II) triflimide salt and hexafluoroisopropanol (HFIP). This method affords a large variety of diaryl alkanes, notably diaryl ethanes, in good to excellent yields, and is simple to implement and compatible with various functional groups. Furthermore,

The copper(I)‐catalyzed alkylation of electron‐deficient polyfluoroarenes with N‐tosylhydrazones and diazo compounds has been developed. This reaction uses readily available starting materials and is operationally simple, thus representing a practical method for the construction of C(sp2)C(sp3) bonds with polyfluoroarenesthroughdirectCHbondfunctionalization. Mechanistically, copper(I) carbene
