Borenium-Ions in Catalytic Aromatic C-H Borylation

The catalytic C-H borylation of (hetero)arenes involving borenium species has witnessed fast development in the past decade. This review aims at summarize recent progress made in this field, with an emphasis on synthetic application and reaction mechanisms.
