Special Issue Information

Dear Colleagues,

The aim of the development of green and sustainable chemistry is to maximize the benefit of chemistry and chemical products introduced to human society, and minimize their side effects on the environment and public health. This Special Issue presents recent developments on green and sustainable techniques for organic synthesis. It covers following four areas: 1) catalysis reactions (metal-catalysis, organocatalysis, and biocatalysis; 2) new reactions and techniques (pot/atom/step economy reactions, C-H functionalization, flow chemistry, microwave, ultrasonic, photolysis, photoredox, mechanochemistry); 3) alternative solvents (biorenewable solvents, aqueous, ionic liquids, SC-CO2); and 4) CO2 and biomass-derived building blocks for 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 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. Molecules 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 1800 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.

N-halosuccinimides (NXSs) are well-known to be convenient, easily manipulable and low-priced halogenation reagents in organic synthesis. In the present work, N-bromosuccinimide (NBS) has been promoted as the most efficient and selective catalyst among the NXSs in the reaction of direct esterification of aryl and alkyl carboxylic acids. Comprehensive esterification of substituted benzoic acids, mono-, di- and tri-carboxy alkyl derivatives has been performed under neat reaction conditions. The method is metal-free, air- and moisture-tolerant, allowing for a simple synthetic and isolation procedure as well as the large-scale synthesis of aromatic and alkyl esters with yields up to 100%. Protocol for the recycling of the catalyst has been proposed. Full article

Tentative title: Immobilized gold(I) nanoparticles prepared from gold(III)-containing ionic
liquids on silica: application to the sustainable synthesis of propargylamines

Abstract: Acycloaurated phosphinothioic amide gold(III) complex was supported on amorphous silica with the aid of an ionic liquid, [bmim]PF_6 . Gold(I) nanoparticles were formed in situ and subsequently immobilized on the SiO_2 -IL phase. The resulting immobilized AuNPs@SILP catalyst were highly efficient in promoting the solvent-free A^3 coupling reaction of alkynes, aldehydes and imines in high yields under solvent-free conditions, with a very low catalystloading  and without the use of additives. Additionally, the AuNPs@SILP has good recyclability and can be reused at least five times in 98-80% yields. This synthetic method provides a green and low cost way to effectively synthetize propargylamines.

Abstract: To circumvent the thermodynamic limitation of the synthesis of oxazolidinones starting from 2-aminoethanols and CO_2 and realize incorporation CO_2 under atmospheric pressure, an ionic liquid facilitated three-component reaction of propargyl alcohols, CO_2 and 2-aminoethanols was developed to produce 2-oxazolidinones and equal amount of α-hydroxyl ketones. The ionic liquid structure, reaction temperature and reaction time were in detail investigated. And 15 mol% [TBDH][TFE] was found to be the most one in this study for this cascade reaction. Under atmospheric CO_2 , 2-aminoethanols with different substituents were successfully transformed to 2-oxazolidinones with moderate to excellent yield after 12 h reaction at 80 ºC.
Keywords: Ionic liquid; 2-oxazolidinone; 2-aminoethanol; propargyl alcohol; CO_2 ; α-hydroxyl ketones
