Room Temperature Acid-Free Greener Synthesis of Imine Using Cobalt-Doped Manganese Tungstate

Facile synthesis of an imine compound through a greener route is still a challenging task. Industrial processes rely on the age-old Schiff reaction for the synthesis of imine, which are reversible and nongreen from an environmental viewpoint. Herein, coba

High-performance, command-degradable, antibacterial Schiff base epoxy thermosets: Synthesis and properties

Two diepoxides containing a two-benzene-ring-conjugated Schiff base when cured with an aromatic diamine result in high-performance thermosets combining excellent controlled degradability, stability and antibacterial properties. Epoxy resins have been wide

One-pot solvothermal synthesized CoS2@MoS2 nanocomposites for selective reduction coupling reaction to synthesize imines

Selective reduction coupling of nitroaromatics and aldehydes for imines synthesis has been investigated by using a series of bifunctional CoS2@MoS2 catalysts prepared by one-pot solvothermal method. Under optimal Co/Mo ratio of 0.75 and preparation temperature (180 °C), CoS2@MoS2–180-0.75 catalyst shows 96.5% nitrobenzene conversion, 93.0% imine selectivity and good versatility for substituted nitrobenzene and different aldehydes under mild conditions (60 °C, 1.5 MPa H2). The characterizations reveal that high nitroaromatics hydrogenation activity and good selectivity are mainly due to the formation of CoMoS phase, the coupling reaction between aniline derivatives and aldehydes is achieved by the appropriate acidity of CoS2@MoS2 nanocomposites.

Synthesis, characterization and theoretical study of a new liquid crystal compound with an oxazepine core

A novel synthesis of heterocyclic liquid crystal compounds containing a seven-membered 1,3-oxazepine with terminal alkyloxy chains has been carried out. The molecular structures of these compounds were substantiated by FT-IR NMR elemental analysis. The relationship between the structures and the mesomorphic behaviours of their derivatives were investigated. The results showed that the formation of mesophases is strongly dependent on the type of core moiety. All compounds with oxazepinediones and oxazepanediones are non-mesogenic and only exhibit Cr1Cr2 upon cooling and heating. However, the SmA and N phases were observed in the 5,6-benzo [1,3] oxazepine-4,7-diones series of compounds. The study also revealed that the length of the alkyl chain has a significant effect on the liquid crystalline properties; the nematic phase can only observed in long-chain derivatives of 5,6-benzo [1,3] oxazepine-4,7-diones. Theoretical studies are in agreement with our result.

Antioxidant activity of synthetic resveratrol analogs: A structure-activity insight

This study evaluated the antioxidant activity of five resveratrol analogs using the DPPH method. The molecules activity was related with their chemical structure. Besides descriptive statistics, the analysis of variance (ANOVA) followed by Tukey's post hoc test were performed (p50 value statistically different from the resveratrol (p0.001), its antioxidant activity was considered satisfactory. The other analogs (D and E), which have a 4-acid grouping in place of 4-hydroxy grouping, showed lower antioxidant activity than resveratrol (p0.001). Further studies to address possible advantages of analogs in relation to resveratrol should be conducted in order to make them feasible for therapeutic use.
