<p>The invention relates to hydroxy-4-2H-1-benzothiopyran-2-ones, represented by the following formula: <IMAGE> (I) in which, when R1 is hydrogen, R and AR' can form a tetrahydronaphtyl cycle; R and R1 can form a carbonyl group; R is a hydroxyl group when R1 is hydrogen; AR is a biphenyl or phenoxyphenyl group, which is substituted or non-substituted by a halogen, and AR' is a substituted or non-substituted phenyl group which may form with R a tetrahydronaphtyl cycle or a thienyl group. These compounds have interesting properties and may be used in particular as rodenticides.</p> |
