Electrochemical pathway to CH/PH functionalization of diphenylphosphine oxide

GRAPHICAL ABSTRACT ABSTRACT Electrochemical oxidative CH/PH functionalization reaction between diphenylphosphine oxide and diphenylacetylene has been performed. The yield of target cyclisation product was obtained with 76% yield after 4F of electricity was passed through the reaction mixture at 1.0 V (vs. Ag/AgCl).
