A general efficient method for the synthesis of phosphoryl isocyanates was developed. The method involves reactions of phosphoryl chlorides with sodium cyanate in the presence of anhydrous magnesium chloride as a catalyst.

A reaction of chlorophosphonates R1R2P(O)Cl with NaOCN and subsequent treatment with octylamine lead to phosphorylureas R 1R2P(O)NHC(O)NHC8H17-n (R 1 = EtO, PhO; R2 = Me, Ph). Their extraction capability toward UVI and a number of tervalent lanthanides (LaIII, NdIII, HoIII, YbIII) was studied. Efficiency and selectivity of these ligands in the extraction of f-elements from nitric acid solutions to chloroform were compared with extraction properties of a model phosphine oxide-type phosphorylurea MePhP(O)NHC(O)NHC8H 17-n and carbamoylphosphine oxide Ph2P(O)CH 2C(O)NBu2.
