CLEAR ORANGE LIQUID

??

Diisopropyl Azodicarboxylate is an azodicarboxylic acid derivative used as a reagent in the production of many organic compounds. Diisopropyl Azodicarboxylate is commonly used as an oxidizer in Mitsun obu reactions and can also serve as a selective deprotectant of N-benzyl groups in the presence of other protecting groups.

?? ??

Reacted with dioxaphosphorinanes and iron catalyst to generate rearranged phosphonium ylide products.

Purification Methods

Purify the azo compound by distillation at as high a vacuum as possible. Since it is likely to explode, use an oil bath for heating the still, and all operations should be carried out behind an adequate shield. [Kauer Org Synth Coll Vol IV 412 1963, Beilstein 3 III 233]. This reagent is useful in the Mitsunobu reaction [Mitsunobu Synthesis 1 1981, Gennari et al. J Am Chem Soc 108 6394 1986, Evans et al. J Am Chem Soc 108 6394 1986, Hughes Org React 42 335 1992, Dodge et al. Org Synth 73 110 1996, Hughes Org Prep Proc Int 28 127 1996, Ferguson & Marcelle J Am Chem Soc 128 4576 2006; see also di-tert-butyl azodicarboxylate and DEAD above].
