WebDiazomethane is an ideal derivatization reagent. The reaction is fast, the yield is high, side reactions are minimal, the by-product is nitrogen gas, and reaction conditions are very mild. Diazomethane is a yellow gas so the progress of the reaction can easily be followed. WebIn the reaction between o -nitropiperonal (IX) and diazomethane, an aryl shift leads to production of the epoxide (X) in 9 to 1 excess of the ketone product (XI). When diazoethane is substituted for diazomethane, a hydride shift produces the ketone (XII), the only isolable product. [26] Effect of Diazoalkane on Migratory Preferences
