An isolatable α-lactone made by direct epoxidation
Abstract
Epoxidation of perfluoro-[(1-ethyl-1-methylpropyl)(1-methylpropyl)]keten with sodium hypochlorite–acetonitrile afforded a high yield of perfluoro-[(1-ethyl-1-methylpropyl)(1-methylpropyl)]-ethanolide, the most stable α-lactone yet to be isolated.
