Nate and Matt provide new mechanistic insight into over-arylation in Suzuki cross-couplings, and the surprising differences between dibromo vs. dichloroarenes. Currently free to read as an ACS editor's choice. pubs.acs.org/doi/10.1021/...

Selectivity for Exhaustive Cross-Coupling of Dihaloarenes Is Affected by the Interplay between the Halide Byproduct, Solvent, and Ligand

In dihaloarene cross-couplings, the step(s) that take place after reductive elimination and before the start of the next cycle influence selectivity for monofunctionalization versus difunctionalizatio...

Dinora's Flash Comm at Organometallics is timely with the beginning of the Astros' Spring Training! The synthesis of these molecules are a home run! pubs.acs.org/doi/10.1021/...

Flash Communication: Synthesis and Isolation of Neutral Pyridine Bis(carbene) Calcium Complexes

A series of 2,6-bis(3-mesitylimidazol-2-ylidene)pyridine (MesCNC) calcium dihalide (X = Cl, Br) complexes have been synthesized by direct treatment of the corresponding imidazolium salt precursor with calcium bis(trimethylsilyl(amide)) (Ca[N(SiMe3)2]2(thf)2), in contrast to previously reported methods. Structural evaluation showed that generating the analogous ligand with substitutions at the 3- and 5-positions of the central pyridine moiety resulted in the 3,5-dimethyl-2,6-bis(3-mesitylimidazol-2-ylidene)pyridine (3,5-Me2-MesCNC)CaI2 complex, which shows puckering of the ligand that has not been observed previously. Attempts to characterize these complexes by solution-state NMR spectroscopy have been previously elusive; herein, we report full characterization of a suite of pyridinebis(carbene) calcium complexes along with single crystal X-ray diffraction studies.

New online! Catalytically competent nickel(I)–isocyanide compounds for cross-coupling reactions

Catalytically competent nickel(I)–isocyanide compounds for cross-coupling reactions

Nature Catalysis, Published online: 14 January 2026; doi:10.1038/s41929-025-01473-9Nickel-catalysed cross-coupling reactions generally use Ni(II) or Ni(0) precatalysts. Here the authors report thermally stable dinuclear Ni(I) complexes with commercial isocyanide ligands for the efficient catalysis in Kumada, Suzuki–Miyaura and Buchwald–Hartwig cross-coupling reactions.

My favorite 2025 #PfizerChemistry publications #12daysOfPapers 1/n: From my La Jolla colleagues this is a cool use of Rh-catalyzed C-H activation followed by retro Diels-Alder to provide useful med chem heterocycles #OrgLett #ChemSky #ChemChat

Microwave-Assisted Synthesis of Heterocycles via Rhodium(III)-Catalyzed C–H Activation: Norbornadiene as an Acetylene Equivalent

General procedures for the rhodium-catalyzed annulation of aryl/heteroaryl O-pivaloyl hydroxamic acids and norbornadiene have been developed. Employing norbornadiene as an acetylene equivalent enables...
