Ortho-substituent effects on diphenylurea packing motifs
Solomos, Marina A.,Watts, Taylor A.,Swift, Jennifer A.
, p. 5065 - 5072 (2017)
Hydrogen bonding between urea groups is a widely used motif in crystal engineering and supramolecular chemistry studies. In an effort to discern how the steric and electronic properties of substituents affect the molecular conformation and crystal packing
Synthesis and structure activity relationships in diphenylureas against Culex quinouefasciatus

Substituted diphenylureas 1-23 have been synthesised from isocyanates generated from azides of benzoic acid and 4-chlorobenzoic acid with aniline, and 4-chloro-, 2-trifluoromethyl-, 3-trifluoromethyl, 4-phenoxy-, 2,4-dichloro-, 2,5-dichloro-, 3,4-dichloro-, 3-chloro-4-methoxy-, 3-chloro-2-methyl-, 3-chloro-4-methyl- and 4-nitro-anilines. All the compounds have been tested for insect growth regulating (IGR) activity against early third instar larvae of Culex quinquefasciatus, the human filariasis vector. Compounds 15 and 19 exhibit 100 percent emergence inhibition at 1 ppm concentration against Cx quinquefasciatus larvae. These compounds may play a useful role in mosquito control by maintaining the vector populations at a minimum level.
