Really honoured 😊🎉 and grateful 🥳 to @MarkLautens @TheLautensGroup for highlighting our recent work in Synfacts ✨.
Thanks @thiemechemistry

Complementing the McMurry Coupling and Alkene Metathesis: Photocatalytic denitrative homo- and cross-coupling of nitroalkanes towards the synthesis of alkenes https://t.co/LGLjNGIall: Back-to-back with the complementary study from the @ParasramLab. The same but not the same 😀

[Reiser-group @reiser_group]

Even better than copper: Mangish @i_am_mangish , Tirtha and Zen have developed a ß-chloroesterification strategy of alkenes by direct excitation of pyridine-N-oxide esters and Fe(II)(bpy)3 as a radical ligand transfer agent. Congrats to all. https://t.co/UYoU0HGSlD

Cu fails ⛔ Fe signs🌟
DeLIGHTed to develop novel, light-driven method for β-chloroesterification of alkenes by synergy of Fe catalyst & pyridine N-oxides.
✅Unprecedented [Fe(bpy)3]2+ as RLT agent ✅LIH of N-O bond. @reiser_group @TIRTHAMANDAL11

Complementing the McMurry Coupling and Alkene Metathesis: Photocatalytic denitrative homo- and cross-coupling of nitroalkanes towards the synthesis of alkenes: https://t.co/jzy0KIMfWA. See the parallel submission by @ParasramLab, the same but not the same 😀

[Reiser-group @reiser_group]

Our study on the photocatalyzed ß-chloroacylation appeared in its final form. Inspiration from the @NgaiLab and Greg Fu's labs helped us to understand the unique dual character of heteroleptic Cu-phenanthroline-phosphine photocatalyst. https://t.co/mHCTi62s2f.

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

A general photocatalytic platform for the regio- and stereoselective β-chloroacylation of alkenes and alkynes using a heteroleptic copper(I) complex https://t.co/3Hn5dTofaM

[Mangish Ghosh 🇮🇳🇮🇳 @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.

@HariGroupIISc @angew_chem @iiscbangalore @ANRFIndia Congratulations🎉

[Mangish Ghosh 🇮🇳🇮🇳 @i_am_mangish]

🎇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 👉 https://t.co/QQ2tMZtJdE.

[Reiser-group @reiser_group]

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; https://t.co/UIn8o13C8i

[Mangish Ghosh 🇮🇳🇮🇳 @i_am_mangish]

📣📣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

@poreyarka Congrats Arka🙂

[Reiser-group @reiser_group]

If I had a hammer...we blatantly destroy bicyclic cyclopropanes to access cyclohexenes with unusual substitution patterns. Great collaboration with the Davies group @EmoryUniversity. https://t.co/J5KkuEG3qg, thank you @JOC_OL, for supporting our destructive approach.
