Arynes are found to be facilely inserted into bis(pinacolato)diboron by using a platinum–isocyanide catalyst, affording diverse 1,2-diborylarenes, which can be converted into o-terphenyls via Suzuki–Miyaura coupling reaction.

We report herein a simple, additive- and metal-free, photoinduced, dualC-H/C-Xborylation of chloro-, bromo-, and iodoarenes. The reaction produces 1,2- and 1,3-diborylarenes on gram scales under batch and continuous flow conditions. The regioselectivity of the dualC-H/C-Xborylation is determined by the solvent and the substituents in the parent haloarenes.
