Latest Patents
Kawamoto's latest patents include a method for the preparation of an N-vinyl compound. This innovative method allows for the efficient synthesis of compounds such as N-vinyl-2-pyrrolidone and N-vinyl-N-ethyl acetamide. The process involves the thermal decomposition of an N-(α-acyloxyethyl) compound, which is formed through an addition reaction between an NH group-containing compound and a vinyl carboxylate in the presence of an alkali. The reaction mixture can be heated to produce the desired N-vinyl compound, which can then be isolated with a high overall yield.
Another significant patent by Kawamoto is for the N-(α-acyloxyethyl) compound and its preparation method. This novel compound can be converted into an important N-vinyl compound through thermal decomposition under mild conditions. The synthesis of the N-(α-acyloxyethyl) compound is achieved through the addition reaction of an NH group-containing compound with a vinyl carboxylate, yielding high results.
