industrial chemical CF3CH2Cl and (hetero)aryl bromides and chlorides has been reported. The reaction is synthetically simple without the preparation of arylmetals and exhibits high functional group tolerance. The utility of this protocol has been demonstrated by the late-stage modification of pharmaceuticals, providing a facile route for medicinal chemistry.

The transition-metal-free 2,2,2-trifluoroethylation and gem-difluorovinylation of arylboronic acids were developed. By employing different reaction conditions, these transformations provide both (2,2,2-trifluoroethyl)arenes and gem-difluorovinylarenes from arylboronic acids and 2,2,2-trifluorodiazoethane. The operation is simple and scalable with good functional group tolerance.
A bis-trifluoroethyl coordinated nickel/bipyridine complex has been developed as efficient precatalyst for diverse Suzuki-type alkylations which features unconventional precatalyst initiation mode.
