ARYL SULFIDE DERIVATIVES AND ARYL SULFOXIDE DERIVATIVES AS ACARICIDES AND INSECTICIDES

The present invention relates to aryl sulphide and aryl sulphoxide derivatives, to their use as acaricides and insecticides for controlling animal pests and to processes and intermediates for their preparation. The aryl sulphide and aryl sulphoxide derivatives have the general structure (I) in which the respective radicals have the meanings given in the description.

Preparation of Imidazoquinazolin-5(3H)-ones and Related Tricyclic Systems Using a Novel, Double Displacement Reaction

New methodology is described for the construction of tricyclic heterocycles.Thus, a double displacement reaction of 1-(2-fluorobenzoyl)-2-methylthio-2-imidazoline (8a) with 1,1-dialkylhydrazines gave 10-substituted 2,10-dihydroimidazoquinazolin-5(3H)-ones in good yield.The corresponding 1-(2-nitrobenzoyl)-2-methylthio-2-imidazolines also underwent double displacement reactiones with hydrazines.Other tricyclics made using double displacement reactions were pyrimidoquinazolines, imidazopyridopyrimidines, and imidazopyrazolopyrimidines.Treatment of 8a with hydrazine hydrate or methylhydrazine gave products resulting from displacement, but did not afford fused benzotriazepinones.
