Orthogonal One‐Pot Dual Catalysis Enabled by a Hybrid Chiral Diene/Phosphine Ligand

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 14, 17 July 2026.
A hybrid chiral diene–phosphine ligand enables orthogonal one‐pot Rh/Pd relay catalysis, delivering high yields and enantioselectivities while outperforming dual‐ligand systems. A hybrid chiral diene‐phosphine ligand (L1) enables orthogonal one‐pot relay catalysis by integrating distinct metal‐coordination sites within a single molecular framework. The

A New Metal‐Ester Bonding Motif for the Synthesis of Hybrid Molecular Catalysts on Metal Oxide Supports Leads to Tunable Reactivity

open access: yesAngewandte Chemie, Volume 138, Issue 29, 13 July 2026.
This work reports a new metal–ester bonding strategy for anchoring molecular catalysts to metal oxide supports, achieving exceptionally high surface loadings. Catalyst reactivity is predictably tuned by the support's properties, enabling control over electronic behavior and reaction pathways, thus opening new possibilities for designing highly ...

Cross‐Carboxylation of Methanol and Other Alcohols With CO2 Into Asymmetric Alkyl Methyl Carbonates Over a CeO2 Catalyst

open access: yesChemistry – A European Journal, Volume 32, Issue 27, 17 July 2026.
One‐pot synthesis of asymmetric organic carbonates from CO2, methanol, and other alcohols was demonstrated in the presence of CeO2 catalyst and 2‐cyanopyridine dehydrant. This reaction proceeded through two reaction pathways—direct route via cross‐carboxylation and indirect route via production of DMC and subsequent transesterification.

Glucose Modulates Marine Xylanase Activity: Insights From Caulerpa lentillifera and Synthetic β‐1,3‐glucoxylans

open access: yesChemBioChem, Volume 27, Issue 13, 14 July 2026.
Two recombinant xylanases from marine bacteria, β‐1,3‐xylanase Xyl4 and mixed‐linkage xylanase AlXyn26A, were used to digest glucoxylan structures extracted from the green alga Caulerpa lentillifera and synthesized by automated glycan assembly. High‐performance liquid chromatography coupled with mass spectrometry (HPLC‐MS) analysis of the reaction ...

Toward Sustainable Carbonylation Reactions Enabled by CO Surrogates in Green Solvents

open access: yesChemSusChem, Volume 19, Issue 13, 14 July 2026.
Carbonylation reactions offer a sustainable route to valuable carbonyl compounds. This review highlights methodologies that exploit carbonylative coupling to drastically enhance process sustainability, avoiding the direct use of CO through CO surrogates and promoting syntheses in green solvents potentially derived from renewable and sustainable sources.

Solvent‐, Catalyst‐, and Heating‐Free Mechanochemical Depolymerization of Polyurethane

open access: yesChemSusChem, Volume 19, Issue 13, 14 July 2026.
A sustainable mechanochemical strategy is developed for polyurethane depolymerization under ambient conditions using only NaOH. Ball milling enables efficient urethane bond cleavage, allowing up to 69% polyol recovery from commercial PU foams within 3 h. This energy‐efficient approach offers a novel route for polyurethane recycling.
