-promoted protocol for the selective and controllable esterification of P(O)OH compounds using O-nucleophiles (alcohols and phenols) as efficient esterification reagents is described. This method features a high efficiency and good functional-group tolerance, meaning a simple way to synthesize a broad spectrum of phosphinic and phosphoric acid esters from basic starting materials with moderate to excellent

Various valuable phosphinothioates and phosphinates including those with functional groups are readily prepared under mild reaction conditions via chloroform-based Atherton–Todd-type reactions of secondary phosphine oxides with alcohols and thiols, respectively.
efficient N,N′-carbonyl diimidazole-catalyzed protocol for the direct esterification of P(O)-OH compounds using phenols as efficient esterification reagents is illustrated. It is a simple way to synthesis a broad spectrum of functionalized O-aryl phosphinates, phosphonates, and phosphates from basic startingmaterials with moderate to excellent yields.

Compared to previous transition metal-catalyzed C-phosphorylation reactions for constructing C–P bonds, in the absence of transition metal catalysts and ligands, a direct O-phosphorylation of aryl triflates selectively occurred with P(O)-H compounds in the presence of a base via the construction of O–P bonds. This transformation proceeds under simple and mild conditions, and provides a new method for
