An efficient, mild, and generally applicable protocol for copper-mediated oxidative decarboxylative coupling of arylpropiolic acids with dialkyl H-phosphonates in water has been developed. Note that the reaction could proceed smoothly under air at relatively low temperature (60 °C), and the addition of isopropanol could successfully suppress the decomposition of dialkyl H-phosphonates in water.
