A metal-free, PPh3-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.
Key words: Arenediazonium Salts, Borylation, Arylboronates
