Abstract

A series of novel trifluoromethylcoumarinyl urea derivatives were designed, synthesized, and characterized by ¹H-NMR, C-NMR, and HR-ESI-MS. The fluorescence spectra of the target compounds were recorded. The spectra show that most of the title compounds glow green with λ of 500-517 nm, while compounds , , , and (compounds named by authors) glow violet with λ of 381-443 nm. Moreover, the herbicidal and antifungal activities of the synthesized compounds were evaluated for their potential use as pesticides. The results indicate that compound against the caulis of and compounds and against the taproot of are equivalent to the commercial herbicide Acetochlor. Nine of the title compounds are more antifungal than commercial fungicide Carbendazim against .
