Platinum-catalysed diborylation of arynes: synthesis and reaction of 1,2-diborylarenes.
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.
