<p>Hydroxyphenyl ketones of the formula: <IMAGE> in which n is 0, 1, 2 or 3, X is C or N and Y is C, N or N->O, the heterocyclic structure containing not more than 2 N atoms as ring members, R1 and R2 are each H, F, Cl, Br, NO2, CH3 or OCH3, R3 is H, Cl, Br, NO2, CN, CH3, OCH3, NH2 or NHCOCH3 and R4 is H, Cl, Br or CH3 or together with R3 is a benzene ring fused at the bond [b], if X is C, and R5 is hydrogen or a group of the formula <IMAGE> if n=1. Processes for the preparation of these compounds are also proposed. The said compounds can be used to control harmful micro-organisms.</p> |
