PROCESSO PARA A PREPARACAO DE AMIDAS LIPIDICAS DE EFEITO PESTICIDA E DE COMPOSICOES PESTICIDAS QUE AS CONTEM

Compound of the formula (I): Q Q(CR =CR )a(CR =CF)(CR =CR )bC(=O)NHR (I) or a salt thereof, wherein Q is a monocyclic or a fused bicyclic ring system each ring containing 5 or 6 ring atoms selected from carbon and optionally one or more heteroatoms at least 1 ring being aromatic, or Q is a dihalovinyl group; Q is an alkyl chain containing 1 to 12 carbon atoms and optionally containing one or two oxygen atoms and/or an unsaturated group -CR =CR -, or -C=C-, wherein R and R are selected from hydrogen or halo; a is 0 or 1; b is O or 1; the sum of a and b is O or 1; R , R , R , R and R are the same or different, and are independently selected from hydrogen, halo and C1-4 alkyl; R is selected from hydrogen and C1-6 hydrocarbyl optionally substituted by dioxalanyl, halo, cyano, trifluoromethyl, trifluoromethylthio or C1-6 alkoxy are disclosed which have pesticidal activity. Pesticidal formulations containing the compounds of the formula (I), their use in the control of pests and methods for their preparation are also disclosed.
