Preparation of Fluorophosphates, Difluorophosphates, Fluorophosphonates, and Fluorophosphites in Fluoride-containing Urea MeltsPhosphoric acid, phosphonic acid, and organylphosphonic acid react on heating in fluoride-containing urea melts in high yields to fluorophosphates, M12PHO2F, organylfluorophosphonates, M1RPO2F, organylpolyfluorophosphonates, M12R1CX(PO2F)2, M13N(CH2PO2F)3, and phosphonoorganylfluorophosphonates, M13R1CX(PO3)PO2F (M1 = K, NH4; R = organic substituent; R1 = H, organic substituent; X = OH, NH2, NR2). The reaction mechanism of the formation of fluorophosphate ions in fluoride containing urea melts is discussed.
