4-Allylphosphaisocoumarins can be prepared in good yield and with high regioselectivity by the reaction of o-ethynyl-phenylphosphonic acidmonoesters with allyl bromide catalyzed by Cut. The present reaction represents the first example of a phosphonic acidmonoestercyclized coupling reaction with alkyl halide.

Pd(OAc)2-catalyzed tandem cyclization–coupling reaction of (o-ethynylphenyl)phosphonicacid monoesters and allyl halides has been developed. This reaction provides an efficient, mild, general and regioselective way to synthesize 4-allylphosphaisocoumarins. A Pd(OAc)2-catalyzed tandem cyclization–coupling reaction of (o-ethynylphenyl)phosphonicacid monoesters and allyl halides has been developed. This reaction
