New online! Bismuth-photocatalysed Heck-type coupling with alkyl and aryl electrophiles
Bismuth-photocatalysed Heck-type coupling with alkyl and aryl electrophiles
Nature Catalysis, Published online: 31 October 2025; doi:10.1038/s41929-025-01438-yThe Heck reaction is widely used in modern organic chemistry. Here the authors provide an alternative approach to common transition-metal catalysis, leveraging access to Bi(II) species thanks to bismuth’s photophysical properties.

🔥 An approach for light-driven, Ni-catalyzed C-heteroatom couplings that: -Couples tough nucleophiles (yes, 3° alcohols!) -Couples electron-rich aryl bromides -Doesn't need a PC -Runs on 100 ppm Ni -Delivers on drug syntheses and late-stage modifications Now on @chemrxiv.org: tinyurl.com/3ss6x24j
Josep Cornella & co-workers @cornellab.bsky.social unveil one-step heteroatom exchange🚀 A Ni(0)-catalyzed route converts #isoxazoles & #oxadiazoles into #pyrazoles & 1,2,4-triazoles🧪 A blueprint for rapid #azole scaffold exploration without de novo synthesis🌟 #nickel 👉 buff.ly/BabxqGG
🚨Calling medicinal chemists🚨: A Suzuki het-het coupling sometimes does not require complex ligands. An air stable Ni would do. Amazing work from Rakan Saeb and Byeongdo Roh. onlinelibrary.wiley.com/doi/10.1002/...
Deciphering the mechanism of oxidative addition of aryl iodides into a red-light active bismuthinidene. Incredible team: Alexios Stamoulis, Mauro Mato, Paolo Cleto-Bruzzese, M. Leutzsch, M. Gil-Sepulcre, A. Cadranel and F. Neese. pubs.acs.org/doi/10.1021/...
Transmetalating a challenging tetrel: introducing aryl-[Si] synthons into bismuth organometallic catalysis. Great work spearheaded by Teresa and Sophia. onlinelibrary.wiley.com/doi/10.1002/...
