Toward Tailored Metastability: Exploring Oxanorbornene Chemical Space for Structure–Stability Relationships With Atypical Furan Diels–Alder Adducts

ChemistryEurope, Volume 4, Issue 5, May 2026.
The furan Diels–Alder reaction is a versatile platform for metastable and biobased molecules and materials. By accessing atypical oxanorbornene adducts, we expand furan Diels–Alder chemistry beyond activated addends and show that cycloreversion stability can be tuned over six orders of magnitude, revealing structure–stability relationships that enable ...

Selective Oxidation of Glycolaldehyde to Glyoxal Using Ruthenium Complex Catalysts

ChemPlusChem, Volume 91, Issue 5, May 2026.
Catalytic synthesis of glyoxal from glycolaldehyde using a ruthenium (II) complex catalyst and O2 gas was performed. Glyoxal yield reached 32%, and further oxidation of glyoxal was negligible. Furthermore, the obtained mixture containing glyoxal was precipitated by reaction with sodium sulfite, and it was confirmed that the sulfite adduct can be ...
