ChemInform Abstract: Phosphoric Amides. Part 10. Base‐Promoted Cyclization of Phosphoric Triamides Bearing the N‐(2‐Chloroethyl) Substituent, and the Interconversion of Cyclic Products.

Abstract

The N‐(2‐chloroethyl)‐N',N''‐diarylphosphoric triamides (I) undergo base‐induced phase‐transfer‐catalyzed cyclization, forming the N‐phosphorylaziridines (II), together with the diazaphospholidines (III).
