ABSTRACT:
The invention is a process for the preparation of such 3-halo-2-hydroxyalkyl carbamates which comprises contacting an epihalohydrin carbonate with a secondary amine-containing compound, wherein the secondary amine has a pKa at which the secondary amine will react with the epihalohydrin carbonate and which does not catalyze the formation of unwanted by-products, in a polar organic solvent under conditions such that a 3-halo-2-hydroxyalkyl carbamate, wherein the carbamate nitrogen is tertiary, is prepared.
