A practical, scalable electrochemical dehydrogenative cross-coupling of P(O)H compounds with thiols, phenols and alcohols in both an undivided cell and a continuous-flow setup is disclosed. Its broad substrate scope (>50 examples), good functional-group tolerance and scalability (>10 g) show potential for practical synthesis. A preliminary mechanistic study suggests that the phosphorus radicals are involved in the catalytic cycle.

A novel copper-catalyzed method for the direct esterification of P(O)-OH compounds using phenols as efficient esterification reagents is illustrated. It is a simple way to generate a broad spectrum of functionalized O-aryl phosphinates, phosphonates, and phosphates from basic starting materials with moderate to excellent yields.

The 31P NMR chemical shifts of a series of meta- and para-substituted phenyl diphenylphosphinates, Ph2P(O)OC6H4-X, have been determined.The δ 31P values exhibit an increasing downfield trend as the electron-withdrawing properties of the substituent X become greater and a reasonable correlation between δ 31P and Hammett-Taft substituent constants is obtained.This trend is opposite to that exhibited in several families of compounds of the type ArP(O)Y2, where δ 31P values show an increasing upfield trend as the electron-withdrawing ability of the substituent in Ar is increased.The results are explained by proposing varying degrees of d-orbital occupancy in the phosphorous-oxygen bonds (P-OAr and P=O) in the series of compounds as a factor influencing 31P chemical shifts.
