A review on catalyst deactivation in the oxidative desulfurization process: Causes and mitigation strategies

In recent years, oxidative desulfurization (ODS) has gained significant attention as a promising solution for removing sulfur compounds from fuel oils, particularly heavy marine fuels, to comply with increasingly stringent environmental regulations. While most ODS studies focus o...

Symmetry-based pulsed DNP and EPR sequences

Pulsed microwave irradiation provides more versatile control over spin dynamics than continuous-wave (CW) methods. This study adapts symmetry-based dipolar recoupling sequences, which are originally designed for magic angle spinning (MAS) NMR, to exploit electron-nuclear interact...

Stereoselective trans -1,4 Polymerization of Isoprene and β -Myrcene Mediated by Iron Complexes Bearing 1,1-Diaryl- N -(quinolin-8-yl)methanimine Ligands

Abstract Although iron has emerged as an earth-abundant alternative for 1,3-diene coordinative polymerization, stereoselective iron systems remain uncommon and are often associated with limited catalytic activity. Here, we report three iron(II) complexes supported by 1,1-diaryl-N...

Coordinative chain transfer homopolymerization and copolymerization of bio‐sourced β ‐myrcene and butadiene promoted by iminopyridine iron complexes

Abstract A family of iron complexes bearing iminopyridine (ImPy) ligands with systematic variations on the N ‐aryl and pyridine moieties was evaluated as pre‐catalysts for the coordinative polymerization of β‐myrcene and butadiene. Upon activation with Al i Bu 3 and trityl borate...
