Preparation of 1-azolyl-3,3-dimethyl-1-phenoxy-butan-2-ones

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 <IMAGE> in which X is N or CH, n is an integer from 0 to 4, and Y 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.
