A compound of formula (i)wherein a represents a bidentate group of the formula -ch2-x-ch2- (wherein x is methylene, sulfur or oxygen), x'c=cy or x'wc-cyz (wherein x, w, y and z are independently hydrogen, hydorxy, acyloxy, alkoxy, alkylsilyloxy, cyano or halogen, or x' and w or y and z together with the carbon to which they are attached form a carbonyl group), provided that a is not ch2-ch2; ar is an optionally substituted phenyl or 5- or 6-membered heterocyclic ring system containing from 1 to 3 heteroatoms individualy slected from nitrogen, oxygen and sulfur atoms, and at least one unsaturation (double bond)between adjacent atoms in the ring, said heterocyclic ring being optionally fused to a benzene ring, wherein the substituents, if present, are selected from halogen atoms, cyano, alkyl, alkenyl, alkynyl, alkoxy, haloalkenyl, alkylthio and alkyl amino groups, any of which groups contain up to six carbon atoms; r is hydrogen or cyano or a group selected from alkyl, aryl, heteroaryl, aralkyl, heteroarylalkyl, alkenyl, aralkenyl, alkynyl, alkoxycarbonyl, alkanesulfonyl, arenesulfonyl, aldenyloxycarbonyl, aralkylocycarbonyl, aryloxycarbonyl, heterocyclylakyl, carbamyl, dithiocarboxyl or x |
