Synthesis of Crosslinked Biopolyesters Catalyzed by Natural Amino Acids

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Highly crosslinked bio‐polyesters were synthesized via the ROCOP reaction between epoxidized sunflower oil and biobased cyclic anhydrides. The resulting materials were comprehensively characterized by FT‐IR, TGA, and DSC. A cross‐linked network in the bio‐based polymers has been confirmed by dynamic mechanical analysis.

Zwitterionic Heavier Pnictinidenes in Redox Catalysis

open access: yesAngewandte Chemie, EarlyView.
Zwitterionic pnictinidenes: A new class of zwitterionic heavier pnictogen species stabilized by bis(N‐heterocyclic carbene)borate ligands is reported, enabling the isolation of Sb and Bi in multiple oxidation states. These thoroughly characterized systems exhibit cationic character and engage in redox catalysis, facilitating catalytic ...

Synthesis of Novel Dihydropyridine‐Iminium Salts Containing a Selenazine Core

open access: yesAsian Journal of Organic Chemistry, EarlyView.
An efficient method to develop novel dihydropyrido[3,2‐e][1,3]selenazines iminium salts. A comparative study of the key reagent selenourea towards thiourea and urea was carried out to assess the contribution of chalcogen to the pathway. DFT (density functional theory) calculations have predicted the optimized minimum energy structure for the hybrid ...
