Special Issue Information
Dear Colleagues,
The field of catalysis continues to evolve towards sustainable and renewable modes of reactivity, less reliant on precious metals, superseded by small molecule, viz., organocatalytic methodologies. The impetus for this shift being the intrinsic non-metal feature of organocatalysis, functional group tolerance and the involvement of multiple attractive noncovalent interactions in such processes. In this context, over the last two decades, hydrogen bond and Brønsted acid organocatalyzed approaches have emerged as promising subsets of catalysis and as such, they continue to receive tremendous attention from research groups. The basis for this being the proven high efficiency and versatility of these modes of catalysis for an ever-expanding list of synthetic transformations. Further hydrogen bond and Brønsted acid catalyzed protocols generally provide chemo-, regio- and stereoselectivity under mild conditions, thereby avoiding the production of by-products.
Inherit mechanistic differences between Brønsted acid catalysis and hydrogen bond catalysis, however, are not always simple to delineate experimentally. The distinction between the two, broadly speaking, being Brønsted acid catalysis involves protonated ion pairs, while hydrogen bond catalysis involves hydrogen bond complexes. This divergent character while often overlooked, nevertheless, is paramount to mechanistic understanding. Computational studies provide an ideal means for differentiating between these two activation modes.
Submissions to this special issue entitled “Exploring Hydrogen Bond and Brønsted Acid Catalysis” are welcome in the form of original research papers or short reviews that reflect the state of research in hydrogen bond catalysis and Brønsted acid catalysis. This includes computational, kinetic and/or experimental focused contributions.

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 2200 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.
