Reaction of acid chloride with diazomethane
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. Web9.10.1 Diazomethane. Diazomethane is attractive as a methylating agent for carboxylic acids and phenols because it reacts quickly and highly efficiently with the production of only N2 as a by-product ( Black, 1983 ). Its natural yellow color is discharged as it reacts, providing automatic indication of reaction progress.
