A process for the preparation of a 5-aryloxy-1-chloro-3,3-dimethyl-2-pentanone of the formula ##STR1## in which R 1 and R 2 each independently is halogen, alkyl having 1 to 4 carbon atoms, alkoxy or alkylthio each having 1 to 2 carbon atoms, halogenoalkyl, halogenoalkoxy or halogenoalkylthio each having 1 to 2 carbon atoms and 1 to 5 halogen atoms, cyclohexyl, dialkylamino having 1 to 4 carbon atoms in each alkyl moiety, nitro, cyano, alkoxy-carbonyl having 1 to 4 carbon atoms in the alkyl moiety, phenyl or halophenyl, m and n each independently is an integer from 0 to 5, and m+n≦5, n comprising reacting 1,1,5-trichloro-3,3-dimethyl-1-pentene of the formula ##STR2## with a phenol of the formula ##STR3## in the presence of a base in a diluent, to produce a compound of the formula ##STR4## and subjecting such reaction product to acid hydrolysis. |
