Reagent for Mitsunobu reaction, selective oxidation of a variety of alcohols


1,1'-(Azodicarbonyl)dipiperidine or ADDP is a versatile reagent, but typically used as a reagent in Mitsunobu reactions. It’s stable golden-yellow crystals, soluble ethanol, ether, THF, and slightly soluble in methanol[1]. ADDP is an Azo-type reagent that enables Mitsunobu reactions with certain substrates that react poorly or fail with DEAD-TPP systems, due to a low acidity of substrates[1]. But except Mitsunobu reaction, ADDP can oxidate a wide variety of primary and secondary alcohols, after alcohols are converted into their bromomagnesium salts. This method has been employed to oxidize a wide range of alcohols incorporating functional groups such as alkenes, epoxides, amines, sulfides, allylstannanes, and allenylstannanes[1]. Acylstannanes can also be prepared by the oxidation of the lithium salt of 1-stannyl alcohols.
