NICKEL-CATALYZED BOLYLATION OF ARYL HALIDES WITH 4,4,6-TRIMETHYL-1,3,2-DIOXABORINANE

摘要

The nickel-catalyzed borylation of aryl iodides and bromides with 4,4,6-trimethyl-1,3,2-dioxaborinane was achieved. The mild reaction conditions employed allowed for the inclusion of common functional groups in aryl halides to be tolerated. A DFT study on the catalytic cycle shows that C-B bond formation occurs through σ-bond metathesis between dialkoxyborane and arylnickel(II) halide intermediates.
