Abstract

Abstract 2, 5-dihydrofuran 1 was galvanostatically oxidized in aqueous electrolytes on Pt and PbO 2 anodes at current densities of 10 to 50 mA cm− 2. Under acidic conditions maleic dialdehyde 2 was obtained on both electrodes with a current efficiency (ce) of up to 50%. In the alkaline region (pH 10) 4-hydroxy crotonic aldehyde 3 (Pt) or 2, 5-dihydrofuranone 4 (PbO 2) become the main products with ce's of 29% and 27%, respectively, depending on ...
