Thirteen novel perillaldehyde-based Schiff base-(thio)urea compounds (5a-5m) were designed and synthesized by using perillaldehyde as starting material. Their structures were analyzed and characterized by FT-IR, 1H NMR, 13C NMR, and ESI-MS. The results of preliminary bioassay showed that, at the mass concentration of 50 mg/L, the inhibition rate of target compound 5f (R = p-FAr) against Physalospora piricola was 90.0% (close to that of the pos. control azoxystrobin), and the inhibition rate of target compound 5d (R = Ar) against Alternaria solani was 91.8% (close to that of the pos. control azoxystrobin). Besides, at the mass concentration of 100 mg/L, the target compounds 5c (R = cyclopentyl), 5i (R = p-CH3Ar) and 5a (R = CH3) exhibited 77.6%, 75.3% and 67.4% inhibition against the growth of rape (Brassica campestris) root, resp. (greater than pos. control flumioxazin). Furthermore, substituted Ph thioureas showed better antifungal and herbicidal activities than substituted Ph ureas. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Recommanded Product: Isopropylisothiocyanate).
Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Recommanded Product: Isopropylisothiocyanate
