Special Issue Information
Dear Colleagues,
No catalysts based on transition metals have lately displayed a selectivity, efficiency, and versatility comparable to those of Pd-catalysts. These catalysts represent a real cornerstone of modern synthetic chemistry. Pd-catalyzed reactions often require prolonged heating and may be plagued by the formation of unwanted side products. The current drive toward cleaner chemistry and chemical engineering has spurred a search for more selective and energy-saving protocols, by means of enabling technologies, such as microwaves and ultrasound. Besides an efficient heat and mass transfer, these techniques may generate high-energy micro-environments and hot spots that strongly enhance reactivity and reaction rates, even at low temperatures. These technical aspects are now becoming economically relevant, as Pd-catalyzed reactions are on the verge of being promoted out of the laboratory toward production scales by means of safe and reliable flow systems. Besides hydrogenations and C-C and C-heteroatom couplings, several other applications have been reported in the recent literature. This Special Issue will deal with the recent advances and future perspectives of physical activation for several types of Pd-catalyzed reactions by means of microwaves and ultrasound.

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.
