Description (English)

Other Notes
Stable, crystalline ester of azodicarboxylate with many advantages over other esters of this diacid: the trichloroethyl esters in reaction products can be removed under neutral conditions, the reagent is more reactive in cycloaddition reactions1,2,3; electrophilic aromatic substitution to give hydrazines or amines4
