Single‐Atom Iron‐Catalyzed Oxidative Esterification: From Methylarenes to the Upcycling of Polystyrene and Lignin‐Derived Feedstocks

open access: yesAngewandte Chemie, Volume 138, Issue 31, 27 July 2026.
Heterogeneous iron‐catalyzed environmentally benign and sustainable CH‐oxidative esterification methodology has been developed for the synthesis of esters. This challenging reaction has been achieved by the rational design of specific single atom iron‐based catalyst with Fe‐N4 active centers, which empowered the oxidative esterification of methyl and ...

Deprotonative C(sp<sup>3</sup>)/C(sp<sup>2</sup>)-H (Multi)Silylation of (Hetero)Arenes Mediated by NaTMP. [PDF]

open access: yesAngew Chem Int Ed Engl
An operationally simple protocol using a strongly basic sodium amide in combination with sterically emcumbered silicon electrophiles enables the deprotonative C–H (multi)silylation of a myriad of (hetero)arenes. Mechanistic investigations highlight the pivotal role of steric and coordination effects in controlling the regioselectivity and efficiency of

Synergistic Silylium‐Ion and Palladium Catalysis Enables Migratory Alkene Silylation With Allylsilanes by Formal C–H/C–Si Metathesis

open access: yesAngewandte Chemie International Edition, EarlyView.
Merging silylium‐ion and palladium catalysis provides a mechanistically distinct route to allylsilanes by formal C–H/Si–H metathesis. Using allylsilanes as silicon proelectrophiles, various allylarenes undergo migrative silylation, selectively yielding (E)‐allylsilanes.

Vicinal Difunctionalization of Alkenes With Ketones and 1,2‐Bis(phenylsulfonyl)ethylene With One‐Electron Oxidation: A Three‐Component Route to Functionalized Vinyl Sulfones

open access: yesChemistryEurope, Volume 4, Issue 10, October 2026.
Three‐component coupling reactions of ketones, alkenes, and 1,2‐bis(phenylsulfonyl)ethylene (BPSE) proceed via one‐electron oxidation with K2S2O8 or Mn(OAc)3. Oxidative deprotonation of enols generates α‐keto radicals that undergo sequential alkene addition and BPSE trapping.

Hydroformylation of Olefins With Paraformaldehyde Catalyzed by a Rhodium(I)/Diphosphine/Diphosphoramidite System

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 34, 11 September 2026.
A new dual‐ligand rhodium catalytic system based on [RhCl(cod)]2, BINAP or BIPHEP, and a diphosphoramidite ligand enables the hydroformylation of olefins using paraformaldehyde as a syngas surrogate. The system efficiently converts vinyl arenes, alkyl olefins, cyclopentene, and allyl acetate with high activity and regioselectivity.

Mitochondrial Mediated Apoptosis Evaluation of Myristicin on Triple Negative Breast Cancer Model Via Bcl2/Bid Pathway

open access: yesCell Biochemistry and Function, Volume 44, Issue 8, August 2026.
ABSTRACT Among 15‐20 cases of breast cancer, triple‐negative breast cancer (TNBC) is the deadliest form of the disease. The most effective form of treatment for this type of cancer is still targeted chemotherapy because it lacks hormone receptors. Myristicin, an active aromatic compound with anticancer properties, is mostly found in nutmeg.
