Tous les composés qui répondent à la formule générale donnée ci-dessus déploient à un degré plus ou moins grand une activité acaricide, ovicide contre les acariens, herbicide de pré-levée et herbicide de post-levée. Certains de ces composés ont de très hauts degrés d'activité acaricide, ovicide contre les acariens ou herbicide à des doses extrêmement faibles, tandis que d'autres doivent être utilisés à des doses plus grandes pour exercer un effet pesticide. En général, les composés de l'invention qui déploient le plus haut degré d'activité herbicide déploient également le plus haut degré d'activité acaricide et ovicide contre les acariens. L'activité acaricide et ovicide contre les acariens est la plus grande chez les composés qui portent un atome d'hydrogène ou un substituant alkyle, alkoxy, cyano, trihalogénométhyle ou halogéno dans l'une des positions ortho du groupe 2-phényle et un substituant alkyle ou halogéno dans l'autre position ortho du groupe 2-phényle. Des composés particulièrement actifs comprennent ceux dans lesquels les substituants ortho sont des groupes relativement petits tels que les radicaux méthoxy, éthoxy, méthyle, éthyle ou halogéno. All the compounds which correspond to the general formula given above display, to a greater or lesser degree, acaricide, mite ovicide, pre-emergence herbicide and post-emergence herbicide activity. Some of these compounds have very high levels of miticide, mite ovicide or herbicide activity at extremely low doses, while others must be used at higher doses to exert a pesticidal effect. In general, the compounds of the invention which display the highest degree of herbicidal activity also display the highest degree of acaricidal and ovicidal activity against mites. The acaricide and ovicide activity against mites is greatest in the compounds which carry a hydrogen atom or an alkyl, alkoxy, cyano, trihalomethyl or halogen substituent in one of the ortho positions of the 2-phenyl group and a substituent alkyl or halo in the other ortho position of the 2-phenyl group. Particularly active compounds include those in which the ortho substituents are relatively small groups such as methoxy, ethoxy, methyl, ethyl or halo radicals.
On a également trouvé que certains de ces composés pesticides ont aussi la propriété d'être d'excellents fumigants. De plus, ces composés sont relativement non toxiques envers les mammifères lorsqu'ils sont utilisés en quantités suffisantes pour détruire les acariens, leurs œufs ou les plantes parasites. It has also been found that some of these pesticidal compounds also have the property of being excellent fumigants. In addition, these compounds are relatively non-toxic to mammals when used in sufficient amounts to destroy mites, their eggs or parasitic plants.

La quantité de catalyseur acide que l'on utilise dans la conduite de la réaction selon le schéma III n'est pas déterminante. En général, pour obtenir une vitesse convenable de réaction, on conduit la réaction en présence d'une proportion d'environ 1 à environ 85% en poids du catalyseur acide sur la base du poids total du solvant réac-tionnel. Des concentrations préférées d'acide vont d'environ 50 à environ 85% en poids sur la base du poids du solvant réactionnel.

Sur le schéma V, Z' est un groupe alkylsulfonyle ou un groupe nitro; ou bien Z' peut aussi être un groupe alkyle ou alkoxy lorsque Ri ou Z"' est un groupe nitro. 15 In Scheme V, Z 'is an alkylsulfonyl group or a nitro group; or Z 'can also be an alkyl or alkoxy group when Ri or Z "' is a nitro group.
Le mode opératoire illustré sur le schéma IV implique la décomposition photosensibilisée d'une 2-diazocycloalcane-l,3-dione dans un solvant aromatique, en présence d'un agent photosensibilisant, de préférence la benzophénone. Dans ce procédé, une 2-diazocyclo-alcane-1,3-dione convenablement substituée est décomposée par voie 20 photochimique pour former le carbène à triplet correspondant qui, à son tour, réagit avec un solvant aromatique convenable pour former la 2-arylcycloalcane-l,3-dione désirée. La réaction de photolyse est conduite sous l'action de rayons ultraviolets ayant une longueur d'onde de plus de 290 nanomètres. Les rayons ultraviolets peuvent être produits à l'aide de toute source classique de lumière ultraviolette de type connu des spécialistes en matière de photolyse.
