P(O)R2 directed Pd(ii)-catalyzed C(sp2)–H acylation†
Abstract
A novel method for the Pd(II)-catalyzed C–H acylation of 2-phosphorylbiphenyl with α-oxocarboxylic acids, aldehydes, alcohols and toluene is described. This reaction provides efficient access to various substituted 2′-phosphorylbiphenyl-2-acyl compounds.
