Pd-catalyzed coupling of β-hydroxy α-diazocarbonyl compounds with aryl iodides: a migratory insertion/β-hydroxy elimination sequence†
Abstract
The coupling of β-hydroxy α-diazocarbonyl compounds with aryl halides is described, which proceeds through a Pd-catalyzed migratory insertion/β-OH elimination sequence. This reaction provides a new route to the synthesis of tetrasubstituted
