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

ABSTRACT The synthesis and mesomorphic properties of novel ester derivatives of three seriesheterocyclic 1,3-oxazepinediones and the 1,3-oxazepandione moiety (a–c) are described. All structures were elucidated by physical measurements and the bonding characteristics of the resulting compounds were substantiated by Fourier transform infrared spectroscopy spectroscopy. Their molecular structures are
Two diepoxides containing a two-benzene-ring-conjugated Schiff base when cured with an aromaticdiamine result in high-performance thermosets combining excellent controlled degradability, stability and antibacterial properties. Epoxy resins have been widely used in coatings, adhesives, composites, electronic packaging materials, etc., but they are arduous to recycle and have no antibacterial activity

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 (p
