Borylation of aryldiazonium ions with N-heterocyclic carbene-palladium catalysts formed without added base

Org Lett. 2003 Nov 27;5(24):4635-8. doi: 10.1021/ol035857q.

Abstract

[reaction: see text] A highly efficient catalytic borylation process with aryldiazonium ions was developed using a carbene-palladium catalyst formed in situ to give arylpinacolatoborane products. An X-ray structure for the N-heterocyclic carbene-palladium complex, used as the catalyst formed from bis(2,6-diisopropylphenyl)-4,5-dihydroimidazolium chloride, was obtained without added base.
