Abstract

A fully heterogeneous metallaphotocatalytic C-C cross-coupling of aryl/vinyl halides with alkyl/allyltrifluoroborates is mediated by bipyridyl-Ni(II)-carbon nitride as a stable and recyclable bifunctional catalyst. This visible-light-mediated heterogeneous protocol enables a sustainable synthesis of diverse valuable diarylmethanes and allylarenes in high efficiency.
