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.

Palladium-catalyzed Suzuki-Miyaura cross-coupling reactions of liquid, unbiased dibromoarenes under mechanochemical conditions selectively afford the monoarylated products. The lower reactivity of the crystalline monoarylated products rela-tive to the liquid starting materials should be attributed predom-inantly to the low diffusion efficiency of the former in the re-action mixture, which results in
