Special Issue Information
Dear Colleagues,
Photoredox/transition metal dual catalysis has emerged as a synergistic platform combining two well-established activation modes. The integration of photoinduced single-electron transfer (SET) with traditional metal cross-coupling has expanded the chemical space by enabling the easy construction of new bonds under mild conditions, from commodity reagents. These protocols have opened new pathways for bond formation that are impossible to reach through traditional methods. Several metallaphotoredox strategies for forging single or multiple C–C or C–X (X = heteroatoms) bonds have been reported. Most of these methods involve the use of metal-based photocatalysts (Ir or Ru) in combination with transition metals (Pd, Ni, Cu, Au, Co, Ti, Cr, Rh, Ru, Fe, or Mn). Notably, organophotocatalysts have been successfully used as alternatives to Ir- or Ru-based photocatalysts. Recently, other photoactivation modes, such as electron donor-acceptor complexes or energy transfer, have been described in synergistic combination with metal catalysis, enabling access to a new chemical space. Additionally, the design and employment of new bifunctional photocatalysts has become a trending topic, as these catalysts can perform both roles by themselves. This issue will cover new advances in the field of metallaphotoredox, including not only the formation of new compounds, but also novel metallaphotoredox combinations and/or mechanistic insights.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
