A mild, efficient, convenient, and scalable method to synthesize phosphinatesviadirectphosphorylationbetween R2P(O)H and ROH was developed. Preliminary mechanistic studies suggest that a carbene‐involving process from CHCl3 to CH2Cl2 facilitates the phosphorylation.
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.
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.
