Synthesis of Gasoline and Kerosene by Heterogeneously Catalyzed (Co‐)Oligomerization of Ethylene, Propylene, and Iso‐Butylene

ChemCatChem, Volume 18, Issue 2, 28 January 2026.
ABSTRACT The heterogeneously catalyzed co‐oligomerization of ethylene, propylene, and iso‐butylene was studied focusing on the production of gasoline and kerosene. Silica‐alumina catalysts were employed with and without nickel loading. Initially, the homo‐oligomerization of iso‐butylene was studied employing a series of catalysts and varying reaction ...

Manganese(I) Complexes Containing Bidentate Pyridinium Amidate (PYA) Ligands for Formic Acid Dehydrogenation Catalysis

ChemCatChem, Volume 18, Issue 2, 28 January 2026.
Mn(N,N′) systems can do it! Complexes combining Earth‐abundant manganese and an economically attractive, phosphine‐free pyridinium amidate ligand catalyze the dehydrogenation of formic acid to release H2 selectively, thus providing access to a catalytic system for hydrogen release from a liquid organic hydrogen carrier with turnover frequencies ...

Pivotal Synthesis of Tetrasubstituted Epoxides from Ketones and α‐Halo B/Si Ylides with Understanding of the Activation Modes

ChemistryEurope, Volume 4, Issue 1, January 2026.
The preparation of diastereoselective 1,1,2,2‐tetrasubstituted borosilylepoxides is described, involving the epoxidation of ketones with α‐monohalo borylsilylmethane reagents. The nature of the ambiphilic reagent suppressed the Boron‐Wittig olefination.

The Chemistry of Subphthalocyanines: Synthetic Strategies for their Axial, Peripheral, and Remote Postfunctionalization

ChemistryEurope, Volume 4, Issue 1, January 2026.
From axial and peripheral reactivity to remote derivatization, the chemical versatility of subphthalocyanines (SubPcs) renders them ideal scaffolds for the design of advanced functional materials. This review assembles the synthetic toolbox, key reaction conditions, and future challenges in SubPc functionalization, guiding the development of next ...
