Abstract
Proposed are an N-(.alpha.-acyloxyethyl) compound, e.g., (N-(.alpha.-acetoxyethyl)-2-pyrrolidone, which is a novel compound and can be converted into an industrially very important N-vinyl compound, e.g., N-vinyl-2-pyrrolidone, by a thermal decomposition reaction under relatively mild conditions as well as a method for the preparation of such an N-(.alpha.-acyloxyethyl) compound. The N-(.alpha.-acyloxyethyl) compound can be synthesized in a high yield by the addition reaction of an NH group-containing compound, e.g., 2-pyrrolidone, with a vinyl carboxylate, e.g., vinyl acetate, in the presence of an alkaline compound such as alkali metal hydroxides.
