Abstract
Catalytic cracking of 4-diazo-2, 2,5,5-tetramethylfuranid-3-one (I) in inert solvents gives the azine of 2, 2, 5,5-tetramethylfuranidine-3,4-dione (V), ketene dimer VI, and 2,2, 5, 5-tetramethylfuranidine-3,4-dione(VII). Treatment of diazoketone I with electrophilic reagents leads to replacement of the diazo group by hydroxyl and chlorine.
