Slightly soluble in water.


It is used in a study of the copper-catalyzed addition of aryboronic acids to azodicarboxyl derivatives providing aryl-substituted hydrazides. It is widely used reagent for the Mitsunobu reaction. It is reactant for preparation of polyfluoroalkylated tripyrazolylmethane ligands, (-)-Hygromycin A via Mitsunobu glycosylation, optically active α,α-disubstituted amino acids via Mitsunobu reaction, aza-β-lactams through [2+2] cycloaddition reactions, glycosyl disulfides, pyridine ether PPAR agonists, S-glycosyl amino acid, building blocks for combinatorial neoglycopeptide synthesis and is a histamine H3 receptor antagonists. It is a reactant for Mitsunobu inversion reactions.


Store in cool dry conditions. Incompatible with oxidizing agents.

Reagent for the Mitsunobu reaction (see Diethyl­ azodicarboxyl­ate, L19348), used in combination with tri-n-butylphosphine as a more powerful system than DEAD for higher pKa nucleophiles: Tetrahedon Lett., 34, 1639 (1993); Tetrahedron, 61, 6218 (2005). Has also been utilized in a selective method for converting primary and secondary alcohols to carbonyl compounds, by reaction of the alcohol with a Grignard reagent, followed by oxidation of the intermediate magnesio-derivative with ADDP: J. Org. Chem., 38, 1652 (1973); Bull. Chem. Soc. Jpn., 2773 (1977).
