Special Issue Information

Dear Colleagues,

Catalysis can be defined as “the causing or accelerating of a chemical change by the addition of a catalyst” and ab initio static or molecular dynamics calculations can be the right tool to face new challenges in science, saving time and experiments. Calculations can generate in silico predictions that then can be tested experimentally. Thus, nowadays, calculations could be defined as one of the catalysts of science. Even though, when we hear about catalysts we automatically think about metal catalysts, organic catalysts that are able to fix CO2 or in silico enzymes that mimethize biological reactions are the present and future of catalysis as well.

This Special Issue aims is to gather the different approaches to catalysis assisted by calculations. Contributions dealing with catalyst development, synthesis, and applications in organic, inorganic and polymer chemistry, biological enzymes, and green processes are particularly welcome. All in all, mechanistic studies and theoretical investigations should demonstrate that they are not only a tool, but a solution to face new challenges in catalysis, with predictions before experiments. Research papers, as well as reviews or perspectives, are welcome.

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 papers will be 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. Catalysts 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 1000 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
Density functional theory (DFT) calculations have been performed to investigate the 2° alcohol oxidation to acetophenone catalyzed by the CuI/L-Proline-2,2,6,6- tetramethylpiperidinyloxy (TEMPO) catalyst system.

Density functional theory (DFT) calculations have been performed to investigate the 2° alcohol oxidation to acetophenone catalyzed by the CuI/L-Proline-2,2,6,6- tetramethylpiperidinyloxy (TEMPO) catalyst system. Seven possible pathways (paths A→F) are presented. Our calculations show that two pathways (path A and path B) are the potential mechanisms. Furthermore, by comparing with experimental observation, it is found that path A—in which substrate alcohol provides the proton to OtBu to produce HOtBu followed by the oxidation of substrate directly to product acetophenone by O2—is favored in the absence of TEMPO. Correspondingly, path B is likely to be favored when TEMPO is involved. In path B, the O–O bond cleavage of CuI–OOH to CuII–OH species occurs, followed by acetophenone formation assisted by ligand (L)2ˉ. It is also found that the cooperation of ligand (L)2ˉ and TEMPO plays an important role in assisting the formation of the product acetophenone in path B. Full article
