N-acylated arylpyrroles, process for obtaining thereof and method of insect control

The invention describes new N-acylated arylpyrroles effective for controlling the insects having the general formula:Where X represents Cl, Br;Y represents Cl, Br or trifluormethyl;L represents hydrogen or halogen;M and Q each independently represents hydrogen or halogen;R represents (C1-C4)alkyl; (C3-C6) alkenyl; (C3-C6) cycloalkyl; phenyl, optionally substituted by 1-2 halogen atoms, (C1-C4) alkyl group, trifluormethyl, nitro; phenoxy or furyl group.The process for obtaining thereof comprises a substituent interaction of the arylpyrroles with the alkaline metal hybride and further N-acylation with the correspondent RCOCl acid chloride.The obtained technical result consists in improving the solubility in the organic solvents and increasing the insecticide activity range of the synthesized compounds.
