Zum Mechanismus der Aziridinsynthese aus 2‐Azidoalkoholen und Triphenylphosphin

On the Mechanism of the Aziridine Synthesis from 2‐Azido‐alcohols and Triphenylphosphine The reaction of selected 2‐azido‐alcohols, their pivalates, and methanesulfonates with triphenylphosphine was investigated. It is shown that the formation of aziridines from 2‐azido‐alcohols proceeds via 1,3,2λ 5 oxazaphospholidines. Furthermore, the first synthesis of the unsubstituted acenaphtene‐1,2‐imine is described.
