Studies on the insecticidal activities of some newN-benzoyl-N′-arylureas
摘要:
AbstractThis paper reports the synthesis and the insecticidal activities of some N‐benzoyl‐N'‐arylureas 4‐arylsubstituted with alkylated or halogenated aroyl moieties. The compounds, tested against some representative insect species, displayed very high activity against Aedes aegypti, especially the halosubstituted derivatives. None of the newly synthesized compounds showed genotoxic activity in the Bacillus subtilis rec‐assay and in the Salmonella‐microsome test.

A convenient and efficient procedure for the Friedel–Crafts acylation of aromaticcompounds with carboxylic acids in the presence of P2O5/SiO2 is described. Both aromatic and aliphatic carboxylic acids reacted easily to afford the corresponding aromatic ketones. The use of non-toxic and inexpensive materials, simple and clean work-up, short reaction times and good yields of the products are the advantages
