Compounds of formula I <CHEM> and salts thereof, in which Ar is aryl; W is N and Z is CR<5>; or W is CR<1> and Z is N or CR<5>; A is S(O)m, -CH=CH-, O or NH; R<1> is hydrogen, optionally substituted alkyl, halogen or R<2><0>S(O)q; R<2> and R<3> are hydrogen, alkyl, alkenyl or alkynyl, each of which is optionally substituted, aryl, heterocyclyl, cyano, halogen, nitro, YR<2><0>, S(O)2NR<8>R<9>, CHO and functional derivatives thereof, NR<8>R<9> or CYNR<8>R<9>; either (i) R<4> and R<7> which may be the same or different, are hydrogen, optionally substituted alkyl, optionally substituted alkenyl, acyl or optionally substituted alkoxycarbonyl, and R<6> is hydrogen, or (ii) R<4> is as defined above and R<6> and R<7> form a bond or R<7> is as defined above and R<4> and R<6> form a bond; R<5> is hydrogen, alkyl, optionally substituted amino or halogen; R<8> and R<9> are the same or different and are hydrogen, optionally substituted alkyl, acyl or aryl, or together with the nitrogen to which they are attached, form a 5 to 7 membered ring which can contain other hetero atoms; R<2><0> is optionally substituted alkyl; Y is O or S; m is 0, 1 or 2; p is 0 or 1; n is 0, 1 or 2; and q is 0, 1 or 2, with the proviso that when W is CR<1> and Z is CR<5> and n and p are both O, R<4> and R<7> are not alkyl, have pesticidal activity especially against insects, acarids and animal endoparasites. |
