Synthesis of Aza‐indeno‐aza‐fluoranthene and Constitutional Isomers by Ring‐Size Selective C–H Activation

open access: yesChemistry – A European Journal, Volume 31, Issue 72, December 23, 2025.
A series of constitutional isomers of aza‐indeno‐aza‐fluoranthene with different ring sizes has been synthesized. Their product distribution was controlled by adjusting parameters such as base, temperature, solvent, or additive in the Pd‐catalyzed direct arylation step, thereby providing an overview about the options to control ring‐size selectivity in

Exploring the Immobilization Strategies of Lewis Bases on Lignocellulosic Bamboo Shavings and their Applications in Cycloaddition of CO2 and CO2 Derivatives

open access: yesAdvanced Sustainable Systems, Volume 9, Issue 12, December 2025.
Biobased bamboo shavings are used to immobilize Lewis base catalysts for CO2 valorization. Two methods are investigated for immobilization of catalysts: covalent isocyanate coupling and silane condensation. The isocyanate method achieves 100% conversion of cyclic carbonate starting from epoxides, whereas the silane method yields glycerol carbonate with
