Ketal Protection of Glycerol for Selective Electrosynthesis of Glyceric Acid in Highly Alkaline Media

open access: yesAngewandte Chemie, EarlyView.
Using a ketal‐protected glycerol derivative (solketal) as the oxidation substrate enables site‐selective electrooxidation that suppresses C–C cleavage on non‐noble catalysts. Highly alkaline conditions promote reactive solketal alkoxide formation, weaken the Cα─H bond to facilitate dehydrogenation, and buffer local acidification, enabling a record‐high
