    摘要: A process for the preparation of a herbicidally active 1-amino-1,3,5-triazone-2,4 (1H,3H)-dione of the formula ##STR1## comprising in a first stage at a temperature from about 0.degree. to 100.degree. C. reacting an isocyanate of the formulaR.sup.1 - NCO (II)with an isothio semicarbazone of the tautomeric formulas ##STR2## in which R.sup.3 and R.sup.4 each independently is hydrogen, alkyl, cycloalkyl, aralkyl o alkyl, cycloalkyl, aralkyl or aryl,thereby to form a urea derivative of the tautomeric formulas ##STR3## in a second stage at a temperature between about -50.degree. and 0.degree. C. reacting the urea derivative with phosgene (COCl.sub.2) in the presence of an auxiliary organic base and in the presence of a diluent, at least about 2 mols of phosgene and at least about 2 mols of the auxiliary base being used per mol of urea derivative, thereby to form a 1-alkylideneamino-1,3,5-triazine-2,4(1H,3H)-dione of the formula V ##STR4## and in a third stage converting the 1-alkylideneamino group to a 1-amino group.

    摘要: In the preparation of a phenoxy-azolyl-butanone derivative of the formula ##STR1## in which X is a halogen atom,Y is a hydrogen or halogen atom, andAz is an imidazolyl radical or a 1,2,4-triazolyl radical,wherein dichloropinacolin of the formulaCl.sub.2 CH--CO--C(CH.sub.3).sub.3is reacted with an azole of the formulaAz--Hand a phenol of the formula ##STR2## in the presence of an acid-binding agent, the improvement which comprises carrying out the reaction in the presence of a water-immiscible organic solvent at a temperature between about 40.degree. and 150.degree. C., adding to the solvent at a temperature between about 0.degree. and +80.degree. C. a mineral acid, thereby to precipitate the mineral acid salt of the phenoxy-azolyl-butanone derivative, and separating such salt. Surprisingly the product does not hydrolyze when standing in contact with the mineral acid solution. The product is a known fungicide.
