Daisuke Hirose, Dr. Tsuyoshi Taniguchi and Prof. Dr. Hiroyuki Ishibashi Recyclable Mitsunobu Reagents: Catalytic Mitsunobu Reactions with an Iron Catalyst and Atmospheric Oxygen Angewandte Chemie International Edition 52
Aerobic recycling: A catalytic amount of a hydrazine reagent is sufficient to promote Mitsunobu reactions in the presence of triphenylphosphine, an iron catalyst, and air. The active form of the catalyst, an azo species, can be readily generated by iron-catalyzed aerobic oxidation. MS=molecular sieves, Pc=phthalocyanine.
