Special Issue Information

Dear Colleagues,

Metal-free catalysis has emerged as important alternative to metal catalysis in the past few decades. Metals, especially some transition metals, are toxic, expensive, rare, and not eco-friendly, which also make them non-sustainable. Therefore, there are increasing needs for more green catalysts without metals. The utility of metal-free catalysts can partially overcome some drawbacks of metal catalysts. Furthermore, in some cases, metal-free catalysis has more advantages, such as unique performance, selectivity, recyclability and substrate tolerance.

In this Special Issue we welcome the submission about all scopes of metal-free catalysts, including but not restricted to carbon-based nanomaterials, small organic molecules, organic/inorganic polymers and other organic/inorganic nanomaterials. The utility of the catalysts includes organic/inorganic chemical reactions, photocatalysis, environmental reactions, etc. The reaction products could be either organics or inorganics. We are hoping your contribution to this issue, which we think will give comprehensive understanding on the metal-free catalysis for the readers interested in these domains.

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.

An efficient direct C(sp3)–H oxidation of diarylmethanes has been demonstrated by this study. This method employs environment-friendly O2 as an oxidant and is promoted by commercially available MN(SiMe3)2 [M = K, Na or Li], which provides a facile method for the synthesis of various diaryl ketones in excellent yields. This protocol is metal-free, mild and compatible with a number of functional groups on substrates. Full article

Tentative title: Recent Advances in Transition-Metal-Free Direct Formation of C-C and C-Heteroatom Bonds
Abstract: Transition-metal-free coupling reactions become an important research center in the synthesis of biaryl compounds and heterocycles in the last few years. Generally, early method for the construction of such molecules involved transition-metal catalysis, but recent advances in the field have witnessed a myriad of elegant reports on transition-metal free reactions. The serendipitous discovery and observation of synthetic chemists have realized that there lies a great potential in exploiting the inherent reactivity of molecules in absence of transition metal. The key to the success of such coupling reactions is the combination use of a strong base, oxidant and a catalytic amount of N-donor ligands. During the past 10 years, there have been significant advances in transition-metal free reactions, especially for the synthesis or functionalization of heterocycles.
In the following article, we will focus on the recent advances in transition-metal free reactions over the past 5 years. These oxidation reactions are classified by the formation of bonds, including C-C bond formation, C-N bond formation, C-O and C-S bond formation, C-P bond formation, C-B formation, and so on. This review will highlight the scope and limits, as well as the mechanism of these transition-metal free reactions. We hope this review will serve as a handy reference for chemists interested in empolying transition-metal free reactions in organic synthesis and those interested in discovering new type of transition-metal free reactions.
