Summary:Procedure for preparing triazinadione herbicides, of formula: **(See formula)** wherein R1 is an aliphatic radical and (a) or R2 is an acylcarboxylic radical and R3 is a hydrogen atom or an aliphatic radical, or (b) or R2 is a hydrogen atom or an aliphatic radical R3 and together with group X, form a divalent radical Z that bonds the nitrogen atom, to which R3 is attached, with the nitrogen atom of the triazine ring, to form a second 5- or 6-membered heterocyclic ring; and X is a hydrogen atom or an aliphatic radical or together with R3 form the divalent group Z; characterized in that it comprises acylating a triazinadione compound of the above formula in which R2 is hydrogen, with a suitable acylating agent, to provide the compound in which R2 is acyl, with the reaction being carried out at temperatures between 30 and 150ºC, preferably between 100 and 120ºC .
