Special Issue Information

Dear Colleagues,

Research on nanoparticle-based catalysts is currently experiencing a fast growth. We are not just dealing with noble metal nanoparticles but also non-noble metals, each type of which has its own special features and particular applications. The improvements achieved in catalytic activity with such nanocatalysts are of great importance, ranging from several environmental to industrially important reactions. However, there are still challenges to overcome in the use of such systems.

The aim of this Special Issue on “Advances in Supported Nanoparticle Catalysts (Volume II)” is to attract leading researchers in supported nanoparticle research in an effort to highlight the latest exciting developments in the field and to promote practical applications. Accepted contributions will include the design, synthesis, and fundamental properties of nanoparticle-based catalysts and their applications to several types of chemical reactions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
The microwave-assisted Sonogashira C-C cross-coupling reaction catalysed by Pd ionanofluids based on bis(trifluoromethane-sulfonyl)imide (NTf2) ionic liquids, [Cnmim][NTf2] (n = 4, 6 or 8), is described here. An organic solvent- and Cu(I)-free methodology running under very mild conditions [...] Read more.
The microwave-assisted Sonogashira C-C cross-coupling reaction catalysed by Pd ionanofluids based on bis(trifluoromethane-sulfonyl)imide (NTf2) ionic liquids, [Cnmim][NTf2] (n = 4, 6 or 8), is described here. An organic solvent- and Cu(I)-free methodology running under very mild conditions was established by creating in situ catalysts from Pd(II) salts and [Cnmim][NTf2]. The microwave-irradiated catalytic systems quickly yielded almost quantitative conversions of 4-bromoanisole and phenylacetylene (model reaction) into the desired 1-methoxy-4-(phenylethynyl)benzene as a single product, and a good recyclability of the Pd ionanofluids.

In this study, we present the highly efficient and rapid synthesis of substituted dihydropyrimidinone derivatives through an ultrasound-accelerated approach. We utilize copper ferrite (CuFe2O4) magnetic nanoparticles as heterogeneous catalysts, employing the well-known Biginelli reaction, under solvent-free conditions. The impact of the solvent, catalyst amount, and catalyst type on the reaction performance is thoroughly investigated. Our method offers several notable advantages, including facile catalyst separation, catalyst reusability for up to three cycles with the minimal loss of activity, a straightforward procedure, mild reaction conditions, and impressive yields, ranging from 79% to 95%, within short reaction times of 20 to 40 min. Furthermore, in the context of fighting COVID-19, we explore the potential of substituted dihydropyrimidinone derivatives as inhibitors of three crucial SARS-CoV-2 proteins. These proteins, glycoproteins, and proteases play pivotal roles in the entry, replication, and spread of the virus. Peptides and antiviral drugs targeting these proteins hold great promise in the development of effective treatments. Through theoretical molecular docking studies, we compare the binding properties of the synthesized dihydropyrimidinone derivatives with the widely used hydroxychloroquine molecule as a reference. Our findings reveal that some of the tested molecules exhibit superior binding characteristics compared to hydroxychloroquine, while others demonstrate comparable results. These results highlight the potential of our synthesized derivatives as effective inhibitors in the fight against SARS-CoV-2. Full article
