Reactions of trichloride of phosphono carboxylic acid with β-dicarbonyl compounds proceed at the active methylene group with the formation of the С-acylation product with a small admixture of the product of O-acylation. The C-acylation products undergo intramolecular condensation to form 1,2-oxophosphorines and compounds of the phosphate structure. The condensation of trichlorides with phenols proceeds
膦酰基羧酸的三氯化物与β-二羰基化合物的反应在活性亚甲基处进行,形成С-酰化产物和少量O-酰化产物的混合物。C-酰化产物进行分子内缩合以形成1,2-氧代膦和磷酸盐结构的化合物。三氯化物与酚的缩合选择性地在羰基碳原子上进行,从而生成C-苯基酯。随着酸性酚的增多,取代产物中的Р–С键发生分裂。
