摘要

A compound of formula (I), wherein one of R<1> and R<2> is hydrogen and the other is a phenyl, pyridyl, pyrimidinyl, pyrazinyl, thienyl, thiazolyl, benzoxazol-2-one or benzimidazolin-2-one ring, said ring being optionally substituted with halogen, C1-6 alkyl, C1-6 haloalkyl, C1-6 alkoxy, C1-6 haloalkoxy, C2-6 alkenyl, C2-6 alkynyl, hydroxy, nitro, cyano or methylenedioxy; R is hydrogen, formyl, C1-6 alkyl (optionally substituted with cyano, CO2(C1-6 alkyl) or phenyl (itself optionally substituted with halogen, C1-6 alkyl, C1-6 alkoxy, C1-6 haloalkyl or C1-6 haloalkoxy)), CH2(C1-6 haloalkyl), CO2(C1-6 alkyl), CO2(C2-6 alkenyl), CH2(C2-6 alkenyl), CH2(C2-6 alkynyl), benzyl (wherein the phenyl ring is optionally substituted with halogen or C1-4 alkyl) or XR<3>; X is O or NR<4>; R<3> and R<4> are, independently, hydrogen, cyano, C1-6 alkyl (optionally substituted with halogen, cyano, CO2(C1-6 alkyl) or phenyl (itself optionally substituted with halogen, C1-6 alkyl, C1-6 alkoxy, C1-6 haloalkyl or C1-6 haloalkoxy)), phenyl (itself optionally substituted with halogen, C1-6 alkyl, C1-6 alkoxy, C1-6 haloalkyl or C1-6 haloalkoxy), C2-6 alkenyl or C2-6 alkynyl; or an acid addition salt or N-oxide thereof, processes for preparing these compounds, compositions comprising them and methods of using them to combat or control insects, acarines, nematodes or molluscs.
