Aseries of new N'-alkylaminothio,N'-arylaminothio (or dithio), and N',N'-thio (or dithio) derivatives ofN'-benzoyl-N'-phenylureas were designed and synthesized as insect-growth regulators with sulfur dichloride or disulfur dichloride as the original reactant. The new compounds were identified by 1H nuclear magnetic resonancee (NMR) spectroscopy, elemental analysis [or high-resolution mass spectrometry (HRMS)], and single-crystal X-ray diffraction analysis. The X-ray results demonstrated that there exist N-S-N or N-S-S-N bonds in these new compounds. In comparison to the parent N-benzoyl-N'-phenylureas, these derivatives displayed better solubility. The insecticidal activities of the target compounds were evaluated. The results of bioassays showed that compounds 1-24 retained the larvicidal activities of the corresponding benzoylphenylureas (BPUs) and some compounds exhibited better larvicidal activities against oriental armyworm and mosquitoes than the parent BPUs. The larvicidal activities of the selected target compounds 1 and 24 against diamondback moth were better than that of the corresponding parent compounds E and triflumuron.

The reaction of tetrasulphur tetranitride (N4S4) (1) with Grignard reagents (2a-h) and organolithium compounds (10a-h) was investigated.It was found that the reaction of (1) with (2) gave the corresponding disulphides (4a-h) in good yields together with 1,5-diaryl-1,3,5,2,4-trithiadiazapenta-2,3-dienes (3a-c), bisarylamino sulphides (5a and b), ammonium thiosulphates (6a-e), and thiosulphonates (7a-d).Reaction of (1) with (10a-f), generated from benzyl sulphides, afforded diaryl disulphides (4a, b, and e) in moderate yields accompanied by trans-stilbenes (11a and b) and 1,2-bisphenylthio-1,2-diarylethanes (12a and b).Reaction of (1) with diphenyl(phenylthio)methyl-lithium (10g), gave diphenyl disulphide (4a), the tetraphenylethylene (11c), and benzophenone (13a), while reaction of sulphur with (10g) afforded 1,2-epithio-1,1,2,2-tetraphenylethane (15) in 52percent yield besides (4a), (11c), and (13c).Reaction of (1) with 9-phenylthiofluoren-9-yl-lithium (10h) gave (4a), bifluorenylidene (11d), 1,1'-bisphenylthiobifluorenyl (12c), fluorenone (13b), fluorenylideneaminosulphenamide (14).
