The invention describes novel 3-cyano-4-sulfenylated-5-alkoxy-1-arylpyrazoles of general formula(I)
wherein typically preferred substituents are:
R is C₁ to C₄ alkyl fully substituted by halogen;
R₁ is C₁ to C₄ alkyl, C₃ to C₆ alkenyl and alkynyl or aralkyl (each of which may be optionally substituted), dialkylaminocarbonyl or a group -P(=X)(Oalkyl)(Salkyl) wherein X is oxygen or sulfur;
R₂, R₃, R₅ and R₆ are each hydrogen or halogen;
R₄ is CF₃, OCF₃, SCF₃, SOCF₃, SO₂CF₃, OCHF₂, halogen or alkyl; and
n is 0, 1 or 2.
The invention further relates to intermediates and processes to make the compounds as well as to compositions thereof and to methods of control of arthopod (especially insect) nematode, helminth, and protozoan pests.
