Title: PPh<sub>3</sub>-Mediated Borylation of Arenediazonium Salts with Bis(pinacolato)diborane
Abstract: Abstract A metal-free, PPh 3 -mediated borylation reaction of arenediazonium salts with bis(pinacolato)diborane has been developed under mild conditions. The process provides an attractive alternative to the traditional preparation of arylboronates, albeit in moderate yields
