Abstract:

<strong>Aims: </strong>This study was designed to synthesis of Naphthopyrans and xanthenes derivatives in green chemistry approach. <strong>Methodology:</strong> New 13-aryl-indeno[1,2-<em>b</em>]naphtha[1,2-<em>e</em>]pyran-12(13<em>H</em>)-ones and tetrahydrobenzo[<em>a</em>]xanthen-11-ones were obtained by multi-component reaction of 2-naphthol, aromatic aldehydes, indane-1,3-dione or 5,5-dimethylcyclohexane-1,3-dione in the presence of (±)-camphor-10-sulfonic acid (CSA) catalyst under ultrasonic irradiation. <strong>Results:</strong> 13-aryl-indeno[1,2-<em>b</em>]naphtha[1,2-<em>e</em>]pyran-12(13<em>H</em>)-ones and tetrahydrobenzo[<em>a</em>]xanthen-11-ones were obtained in high yields. However, 13-aryl-indeno[1,2-b]naphtha[1,2-e]pyran-12(13H)-one derivatives gave better yields under this conditions. <strong>Conclusion:</strong> The desired compounds were obtained in high yields in short reaction times. The advantages of this method are using a powerful nontoxic, inexpensive, eco-friendly, recyclable, easy to handle, and water-soluble organo-catalyst, building several new bonds in one-pot multi-component reaction, low power consumption, short reaction times and high yields.

Abstract:

AbstractA novel core–shell structured magnetic cobalt oxide supported organosilica-sulfonic acid (Co3O4@SiO2/OS-SO3H) nanocomposite is prepared through a low-cost, simple, and clean method. The characterization of Co3O4@SiO2/OS-SO3H was performed by using Fourier transform infrared (FT-IR) spectroscopy, thermal gravimetric analysis (TGA), powder X-ray diffraction (PXRD), energy dispersive X-ray (EDX) spectroscopy, scanning electron microscopy (SEM), vibrating sample magnetometer (VSM), and transmission electron microscopy (TEM). The TGA and FT-IR results illustrate the high stability of the designed nanocomposite. The SEM image showed a size of about 40 nm for the Co3O4@SiO2/OS-SO3H nanoparticles. Furthermore, according to the result of VSM analysis, the saturation magnetization of this nanocomposite was about 25 emu/g. This novel material was used as an efficient nanocatalyst for the synthesis of biologically active tetrahydrobenzo[a]xanthen-11-one derivatives. These products were obtained in high to excellent yields under green conditions. The recoverability and reusability of this catalyst were also investigated under applied conditions.

Abstract:

Background: Ag–TiO2 nanoparticles catalyzed synthesis of 12-aryl-8,9,10,12-tetrahydrobenzo[a]-xanthen-11-ones have been enhanced via a three-component one-pot reaction betweenβ–naphthol, several aldehydes and dimedone in H2O at room temperature. Xanthenes are essential intermediates in chemistry owing to their vast difference in biological activity. Methods: This process offered significant advantages containing appropriate cost efficiency, low amount of the catalyst, application of low-cost available Ag–TiO2 nanoparticles catalyst, purification of the product by non-chromatographic method, easy process, good atom economy, simple isolation and reusability of nanocatalyst. Result: Ag–TiO2 nanoparticles catalyst shows easy access to Xanthenes with appropriate yields in short reaction time and purity. This nanoparticles catalyst was recycled and recovered by easy filtration and was reused up to five times with only an unimportant loss in its catalytic efficacy. Conclusion: This method achieves to have a numerous scope relating to the difference in the aldehydes. Correspondingly, the attractive of this research was that H2O was the only by-products.

Abstract:

Synthesis and catalytic application of polymeric-based nanocomposites are important subjects among researchers due to their high lipophilicity as well as high chemical and mechanical stability. In the present work, a novel nanocomposite material involving ionic liquid and high-density polyethylene supported tungstate (PE/IL-WO4=) is synthesized, characterized and its catalytic application is investigated. The coacervation method was used to incorporate 1-methyl-3-octylimidazolium bromide ([MOIm] [Br]) ionic liquid in high-density polyethylene, resulting in a PE/IL composite. Subsequently, tungstate was anchored on PE/IL to give PE/IL-WO4= catalyst. The PXRD, FT-IR, EDX, TGA, and SEM analyses were used to characterize the PE/IL-WO4= composite. This material demonstrated high catalytic efficiency in the synthesis of bioactive tetrahydrobenzo[a]xanthen-11-ones under green conditions. The recoverability and leching tests were performed to investigate the stability and durability of the designed PE/IL-WO4= catalyst under applied conditions.
