Special Issue Information

Dear Colleagues,

Nowadays, the demand for cost-effective and sustainable methodologies for the activation or synthesis of new molecules, valorization of biomass resources and waste, environmental remediation and energy conversion is continuously growing as a result of industrial and environmental requirements. Catalysts can play a fundamental role when it comes to this subject. This Special Issue embraces original research articles or relevant critical reviews on the recent achievements, current challenges and future opportunities in the field of new frontiers in organometallic catalysis. Submissions are welcome especially (but not exclusively) in the following topics:

  • Molecule activation
  • Development of cost-efficient catalytic methodologies
  • Synthesis of value-added compounds
  • Applications in organic synthesis and pharmaceutical industry
  • Sustainable chemical catalysis
  • Environmental catalysis
  • Valorization of biomass resources and plastic waste
  • Energy conversion
  • Catalytic materials
  • Applications in asymmetric synthesis

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. 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 2700 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.

Five- and six-membered ring lactones and lactams are ubiquitous frameworks in various natural and synthetic molecules and are key building blocks in organic synthesis. Catalytic addition of an O-H or N-H bond across an unactivated C–C double bond is an appealing approach to rapidly access such highly valuable N- and O-containing skeletons in a waste-free and 100% atom efficient process. Herein, we report, for the first time, the efficient and high-yield cyclization of δ/ε-alkenoic acids and N-protected δ-alkenamides catalyzedby practical and easily accessible Lewis acid scandium(III) triflate under thermal and microwave conditions. The selectivity outcome of the reaction of δ/ε-alkenoic acids was dependent on the substitution patterns of the backbone chain and alkene moiety, leading to the exclusive formation of either the corresponding γ/δ-lactones via an O-selective cyclization or the Friedel–Crafts-type product by C-selective cyclization. An uncommon and rarely disclosed O-selective cyclization occurred preferentially or exclusively when N-protected δ-alkenamides were engaged in the reaction. The atom selectivity of the cyclization was unambiguously confirmed by single crystal X-ray crystallography. Full article

Sustainable synthesis of pharmaceuticals is one of the main challenges for the pharmaceutical industry. Production of these compounds from plastic waste can provide an innovative and ecological approach to their sustainable synthesis. In this context, plastic waste can be regarded as a potential cheap resource for the production of compounds of interest to the pharmaceutical industry. In this work, the first methodologies for the reductive depolymerization of poly(4-hydroxybutyrate) (P4HB) and polybutylene succinate (PBS) plastic waste are reported using the catalyst systems MoO2Cl2(H2O)2/silane, MoO2Cl2(H2O)2/borane and KOH/PhSiH3 with moderate to excellent yields. We also developed the first synthetic strategy for the synthesis of a drug, the anticancer busulfan, from P4HB and PBS plastic waste with moderate overall yields. Full article
