Abstract
Hydroxyphenyl ketones of the formula: ##STR1## in which n is 0, 1, 2 or 3, X is C or N and Y is C, N or N.fwdarw.O, the heterocyclic structure containing not more than 2 N atoms as ring members, R.sub.1 and R.sub.2 are each H, F, Cl, Br, NO.sub.2, CH.sub.3 or OCH.sub.3, R.sub.3 is H, Cl, Br, NO.sub.2, CN, CH.sub.3, OCH.sub.3, NH.sub.2 or NHCOCH.sub.3 and R.sub.4 is H, Cl, Br or CH.sub.3 or together with R.sub.3 is a benzene ring fused at the bond [b], if X is C, and R.sub.5 is hydrogen or a group of the formula ##STR2## if n=1. Processes for the preparation of these compounds are also proposed. The said compounds can be used to control harmful micro-organisms.
