A simple and efficient synthesis of aminopyrazoles substituted with a phospkino oxide and sulphide groups in the 4-position 1 is described. The key step is a regioselective addition of fithiated [~hydrazonophosphine oxides 2 to isocyanates and isothiocyanates to give functionalized amides 3 and 7. S
