Process for the manufacture of insecticidal, nematicidal and acaricida 2-aryl-3-substituted-5-(trifluoromethyl) pyrrole compounds from N-(substituted benzyl)-2,2,2-trifluoroacetimidoyl chloride compounds.

摘要

There is provided a process for the manufacture of insecticidal, nematicidal and acaricidal 2-aryl-3-substituted-5-(trifluoromethyl)pyrrole compounds via the condensation of an N-(substituted benzyl)-2,2-2-trifluoroacetimidoyl chloride compound with an alpha -halo- alpha , beta -unsaturated nitrile, ester or nitro compound.
