N,N‘-Ditosylhydrazine: A Convenient Reagent for Facile Synthesis of Diazoacetates

A novel entry to the synthesis of diazoacetates is disclosed. A variety of diazoacetates were synthesized from the corresponding bromoacetates by treatment with N,N'-ditosylhydrazine in moderate to high yields. Ease of operation with the stable crystalline reagent as well as a short reaction time offer a useful alternative to the conventional methods.
