Insecticidal compounds

Abstract

The present invention provides compounds of formula (I): whereinA, A, Aand Aare independently of one another C—H, C—R, or nitrogen;B-B-B-Bis —CH—C═N—CH—, —CH—N—CH—CH—, —CH—C═CH—O— or —CH═C—CH—O—;Gis oxygen or sulfur;L is a single bond or C-Calkylene;Ris hydrogen, C-Calkyl, C-Calkylcarbonyl-, C-Calkoxy, C-Calkenyl, C-Calkynyl, C-Calkoxy-C-Calkyl, aryl or aryl substituted by one to three R, or Ris heterocyclyl or heterocyclyl substituted by one to three Ror C-Calkoxycarbonyl-;Ris hydrogen, C-Chaloalkyl or C-Calkyl;Ris C-Chaloalkyl;Ris aryl or aryl substituted by one to three R, or Ris heterocyclyl or heterocyclyl substituted by one to three R;Yis CRR, C—O or C═S;Y, Yand Yare independently CRR, C═O, C═S, N—R, O, S, SO or SO;wherein at least two adjacent ring atoms in the ring formed by Y, Y, Yand Yare heteroatoms;each Rand Ris independently hydrogen, halogen, C-Calkyl, or C-Chaloalkyl;and R, R, R, Rand Rare as defined in the claims. The invention also relates to processes and intermediates for preparing these compounds, to insecticidal, acaricidal, nematicidal and molluscicidal compositions comprising these compounds and to methods of using these compounds to control insect, acarine, nematode and mollusc pests.
