The hydroboration of alkenes is an established method for alkylboron synthesis. When the hydroboration of alkenes occurs with concomitant CC bond formation, this can be highly beneficial for the construction of alkylboronates possessing complex structures. Borylative ring-closing reactions can be achieved based on this concept of 1,2-carboboration when alkenes bearing leaving groups are employed. Copper catalysts are mainly used for these processes.
