Abstract
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 selectively at the carbonyl carbon atom leading to C-phenyl esters. With more acidic phenols the splitting of the Р–С bond in the substitution product occurs.
