Derivatives of N-phenylpyrazoles

N-Phenylpyrazole derivatives of the formula: ##STR1## wherein R.sup.1 represents cyano, nitro, halogen, acetyl or formyl; R.sup.2 represents R.sup.5 SO.sub.2, R.sup.5 SO or R.sup.5 S in which R.sup.5 is optionally halogen substituted alkyl, alkenyl or alkynyl; R.sup.3 represents a hydrogen atom or a group NR.sup.6 R.sup.7 wherein R.sup.6 and R.sup.7 each represent hydrogen, alkyl, alkenylalkyl, alkynylalkyl, formyl, optionally halogen substituted alkanoyl, optionally halogen substituted alkoxycarbonyl, or alkoxymethyleneamino, halogen, or R.sup.6 and R.sup.7 together form a cyclic imide and R.sup.4 represents a substituted phenyl group possess arthropodicidal, plant nematocidal, anthelmintic and anti-protozoal properties; their preparation, compositions containing them and their use are described.

Derivatives of n-phenylpyrazoles

The invention relates to isoxazole derivatives of formula (I): ##STR1## wherein: Ar represents phenyl optionally substituted by from one to three groups and wherein two substituents on adjacent positions of the phenyl ring, together with the two atoms to which they are attached, form a 5- to 7-membered ring which is optionally substituted;
