摘要:
In the reaction of 1-chloro-3,3-dimethylbutan-2-one with a phenol to form an ether-ketone, halogenating it to form a halogenoether-ketone and reacting it with imidazole or 1,2,4-triazole to form a 1-azolyl-3,3-dimethyl-1-phenoxybutan-2-one of the formula ##STR1## in which X is N or CH,n is an integer from 0 to 4, andY each independently is halogen, phenyl, phenoxy, nitro, alkyl, alkoxy or cycloalkyl,the improvement which comprises effecting all steps successively in an aromatic hydrocarbon or chlorinated aliphatic or aromatic hydrocarbon as solvent without intermediate isolation. The products are obtained in high yield.

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.
