Visible-light mediated ATRA using a heteroleptic Cu(I) complex!!! Check out our recent article @NatureCatalysis on chloroacylation of wide range of olefins utilizing the adaptive ligand environment around Cu @reiser_group @i_am_mangish
Visible-light mediated ATRA using a heteroleptic Cu(I) complex!!! Check out our recent article @NatureCatalysis on chloroacylation of wide range of olefins utilizing the adaptive ligand environment around Cu @reiser_group @i_am_mangish
📌So, having two different ligands around Cu is better. This time it opens up 🔓simply unprecedented reactivity for 1,2-difunctionalization of olefin which is now hot from the press🤟 @NatureCatalysis. @reiser_group @TIRTHAMANDAL11 #photoredox #catalysis nature.com/articles/s4192…
🎇Happy to share that our work on electrochemical 2+2+2 cycloaddition forming substituted pyridines🔋♻️has been highlighted in #synfacts_of_the_month by @thiemechemistry ☺️☺️. Thanks to the contributors 👍. Get full access of the paper @angew_chem 👉 doi.org/10.1002/anie.2….
Electrochemical Homo- and Crossannulation of Alkynes and Nitriles for the Regio- and Chemoselective Synthesis of 3,6-Diarylpyridines (O. Reiser and co-workers) @reiser_group @i_am_mangish @TIRTHAMANDAL11 @m_lepori @BarhamLab @RehbeinResearch #openaccess onlinelibrary.wiley.com/doi/10.1002/an…
Mangish kept his eyes open in his copper-photo-electro project: no photo, no copper: electro-[2+2+2]-cyclization between alkynes (same or different ones) and nitriles. Congrats team, collaborators @RehbeinResearch @BarhamLab; thanks to @idk_pec; @crc_325; doi.org/10.1002/anie.2…
📣📣Thrilled to share our recently accepted article 📄 in @angew_chem where we have tried to synthesize 3,6-Diarylpyridines electrochemically 🔋🧪. A huge thanks and congratulations 👏🎉 to @TIRTHAMANDAL11, @m_lepori and our supervisors @reiser_group @BarhamLab @RehbeinResearch
Efficient Synthesis of Cyclohepta[b]indoles and Cyclohepta[b]indole-Indoline Conjugates via RCM, Hydrogenation, and Acid-Catalyzed #RingExpansion: A Biomimetic Approach (@TIRTHAMANDAL11, Jyotirmayee Dash and co-workers @DashLab1) onlinelibrary.wiley.com/doi/10.1002/ch…
Transition metal-free, electrochemical [2+2+2]-cycloaddition: Homo(!)- and Hetero(!!)coupling of two (different(!!)) alkynes and nitriles: batch or flow. Congrats Mangish, Tirtha, and Mattia; a great collaboration with @BarhamLab and @RehbeinResearch. dx.doi.org/10.26434/chemr…
If I had a hammer...we blatantly destroy bicyclic cyclopropanes to access cyclohexenes with unusual substitution patterns. Great collaboration with the Davies group @EmoryUniversity. doi.org/10.1021/acs.or…, thank you @JOC_OL, for supporting our destructive approach.
Out now in its final version. Check out the great contributions of many groups in the area of Cu(II)-photocatalysis. Thanks to @ChemicalScience for the speedy and professional processing of our manuscript. doi.org/10.1039/D3SC00…
Cu(I)- or Cu(II)-photocatalysis, why not both? Combining two light-mediated transformations triggered by Cu(II) and Cu(I) in a consecutive way. Congrats Tirtha @MSCActions, Narender @DAAD_Germany, and Hendrik @crc_325. doi.org/10.1021/acsorg… #copper_rocks
Merging Cu(I) and Cu(II) Photocatalysis: Development of a Versatile Oxohalogenation Protocol for the Sequential Cu(II)/Cu(I)-Catalyzed Oxoallylation of Vinylarenes By Oliver Reiser et al @uni_regensburg 🔓 Open access in ACS Organic & Inorganic Au 👉 go.acs.org/4Xy
A new kid on the block: Light-induced homolysis of Cu(II)-substrate complexes. See what is possible, featuring exciting developments by @CastellanoGroup, @RehbeinResearch, @RovisGroup, @uwyoongroup, @ritter_lab, @MacMillan_Lab groups, among others. dx.doi.org/10.1039/D3SC00…
Cu(II) efficiently interacts with transient radicals, allowing the bromonitroalkane addition to alkenes, e.g. for the synthesis of cyclopropylamines. Spectroscopy was key, great collaboration with @RehbeinResearch, congrats to all. doi.org/10.1002/anie.2…
A C-C-bond forming ATRA reactions with broad scope (activated, unactivated alkenes; which ones did we miss?) and useful applications for drug synthesis. EPR studies @RehbeinResearch reveal that copper makes the difference! Congrats to all! onlinelibrary.wiley.com/doi/10.1002/an…
Rapid Access to Substituted Indenones through Grignard Reaction and Its Application in the Synthesis of Fluorenones Using Ring Closing Metathesis by Jyotirmayee Dash and co-workers (@DashLab1 @TIRTHAMANDAL11) onlinelibrary.wiley.com/doi/10.1002/ej…
Merry Xmas, Frohe Weihnachten, Joyeux Noël, feliz Navidad, کریسمس مبارک क्रिसमस की शुभकामनाएं, สุขสันต์วันคริสต์มาส, vesel božič, Buon Natale, メリークリスマス.
Bringing your coworkers together to tell a story: Developing divergent ATRA reactions that fuse to a synergistic cyclopentanol anellation. Congrats Narender, QuanQing, and Tirtha, thx @DAAD_Germany, @crc_325, and @MSCActions for being a matchmaker. doi.org/10.1021/acscat…
You need to have a good reason not to use copper-based photocatalyst in our group: Congrats to Anurag who shows direct C,H-activation of aldehydes by iron/organophotocatalysis, great collaboration with our partners in Chile. doi.org/10.1021/acscat…
The news is out: ORCHEM 2024 😍will take place in Regensburg! Thanks and all the best to @ChemistryKoenig and @reiser_group #ORCHEM2022
