The preparation of a number of N,N′-di-p-tolyl-O-alkyl pseudourea ethers through the alkoxide catalyzed exothermic addition of alcohols to di-p-tolyl carbodiimide is described. Triethyl amine is not effective as a catalyst for such additions. Dicyclohexylcarbodiimide has been found not to undergo such additions at all.The N,N′-diaryl-O-alkyl pseudourea ethers decompose in the presence of mono-and disubstituted
