Abstract

Organic Phosphorus Compounds. XVI. On the Chemistry of the Isocyanatophosphoric Acid Diethyl Ester A one‐pot procedure for preparing ureidophosphoric acid dialkyl esters 2 from POCl3, urea, and alcohols via ureidophosphoric acid dichloride 1 was worked out. 2 (REt) was used as starting material for isocyanatophosphoric acid diethyl ester (4, REt), the reaction of which with anilines and various other primary amines afforded a series of new N'‐substituted ureidophosphoric acid diethyl esters 5 a–k.
