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.
有氧循环:在三苯基膦,铁催化剂和空气的存在下,催化量的肼试剂足以促进Mitsunobu反应。铁催化的好氧氧化很容易产生催化剂的活性形式(偶氮类)。MS =分子筛,Pc =酞菁。
