説明

Alkylation of the nitrogen atoms in the urea moiety of N-benzoyl-N′-phenylureas was extensively carried out, and the alkylated molecules showed the remarkably decreased toxicity against the aqueous invertebrate. From the 1H-NMR studies, it was suggested that the intramolecular association complex was formed in the solution of the non-alkylated N-benzoyl-N′-phenylurea, while such an association was not observed in the alkylated compounds. And it was assumed that the lack of these interactions might be related to the decrease in the toxicity to the aqueous invertebrate. Among the alkylated derivatives, N-benzoyl-N′-methyl-N′-phenylurea showed the highest insecticidal activity. As to the phenyl portion, phenoxyphenyl or biphenyl group substituted with lipophilic groups was favorable.
