Abstract: Dihydropyran (DHP) undergoes autocatalyzed hydration to 2-hydroxytetrahydropyran (2-HY-THP) by carboxylic acids formed in situ in both batch and continuous flow reactors. NMR, GC–MS, and pH analysis corroborate the presence of carboxylic acids in the hydration… read more here.

Abstract: In recent years, N-heterocyclic carbenes (NHC) have gained recognition as versatile molecules capable of acting as organocatalysts in various reactions, particularly through the activation of aldehydes via Breslow-type adducts. This organocatalytic activation has enabled the… read more here.
