Abstract

Pd-catalyzed cross-coupling reactions of diazo compounds have recently emerged as a new type of cross-coupling reaction. 1–4 We have reported a Pd-catalyzed cross-coupling reaction of α-diazocarbonyl compounds with boronic acids, which affords α,β-unsaturated carbonyl compounds in high yields. 1e The reaction presumably proceeds through a migratory insertion process of the Pd carbene intermediate. 5 To further extend the scope of this cross-coupling ...
