Special Issue Information

Dear Colleagues,

In the last few years, visible light photochemistry has received enormous attention as a powerful strategy to enable unprecedented transformations in organic synthesis. The ability of transition-metal-based or organic photocatalysts to harvest visible light and convert it into an electrochemical potential has offered ample opportunities for the construction of functionalized architectures from simple and readily available substrates. By now, visible-light-mediated reactions have been not only applied to simple oxidations and reductions but also widely extended to a large range of important organic transformations, including diverse carbon-carbon and carbon–heteroatom bond-forming reactions. This Special Issue is focused on “Visible-Light-Mediated Reaction: Something Old and Something New”, featuring the state-of-the-art and aiming at highlighting the recent advances in this very fruitful field. Research and review papers related to the development of visible-light-driven homogeneous and heterogeneous transformations are both welcome in this Special Issue. In addition, innovative photocatalyst design as well as mechanistic studies in photochemical reactions will also be considered.

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. Molecules is an international peer-reviewed open access semimonthly 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.

Abstract
We present the first example of visible-light-mediated multicomponent annulation of 1,7-diynes by taking advantage of quadruple cleavage olf carbon-halogen bonds of BrCCl3 to generate a C1 synthon, which was adeptly applied to the preparation of skeletally diverse 3-benzoyl-quinolin-2(1H)-one acetates in [...] Read more.
We present the first example of visible-light-mediated multicomponent annulation of 1,7-diynes by taking advantage of quadruple cleavage olf carbon-halogen bonds of BrCCl3 to generate a C1 synthon, which was adeptly applied to the preparation of skeletally diverse 3-benzoyl-quinolin-2(1H)-one acetates in moderate to good yields. Controlled experiments demonstrated that H2O acted as both oxygen and hydrogen sources, and gem-dichlorovinyl carbonyl compound exhibited as a critical intermediate in this process. The mechanistic pathway involves Kharasch-type addition/6-exo-dig cyclization/1,5-(SN”)-substitution/elimination/binucleophilic 1,6-addition/proton transfer/tautomerization sequence. Full article
