three component cascade phosphorylation of carbazoles, indoles,phenols, alcohols, and thiols with Ph2PH has been well developed. A variety of organophosphorus compounds containing P(O)−X ( X=N, O, S) bonds are produced in moderate to excellent yields (50 examples, up to 97 % yield).

We report a direct and green electrochemical oxidative cross-dehydrogenative coupling reaction of N-heterocycles with hydrogen phosphoryl compounds under external oxidant-free conditions. Various phosphorylation products of substituted carbazoles and indoles are assembled in modest to excellent yields. A hydrogen release process is preliminarily demonstrated and H-2 is the sole byproduct. An imidazolium based ionic liquid is selected as the optimal electrolyte.
