F. Gregan et al., N,N-BIS(2-ALKOXYPHENYL)UREAS AS BY-PRODUCTS IN THE REACTION OF TERTIARY ALCOHOLS WITH 2-ALKOXYPHENYL ISOCYANATES, Chemicke zvesti, 47(4), 1993, pp. 240-242
Primary and secondary alcohols are known to react with aryl isocyanate
s to give arylcarbamates, while tertiary alcohols produce diarylureas.
In this work we used two tertiary alcohols, 2-methyl-1-dimethylamino-
2-propanol and 1-dimethylaminomethylcyclohexanol, to demonstrate that
when reacting with 2-alkoxyphenyl isocyanates a mixture of products wa
s obtained, the 2-alkoxyphenylcarbamates being the main products of th
e reaction.
