PQ-Bis-and P, P, P-tris (1-aziridiny1) phosphoramides containing aryl-substituted aziridine moieties, including para-substituted 2-phenylaziridines, an optically active aziridine, and all the possible C-aryl regioisomers of diphenylaziridine were prepared by condensation of the aziridines with the appropriate phosphoryl chlorides. For the preparation of the sterically hindered diphenylaziridine derivatives, an efficient phosphorylation procedure was ...
