Abstract
Abstract 2-Alkoxyoxetanes are produced by the reaction of an aldehyde or ketone with a vinyl ether in the presence of ultraviolet light. The 2-alkoxyoxetanes produced in accordance with this invention are useful as plasticizers for organic resins, as intermediates for making 3-hydroxy-alkyl ethers utilizing an appropriate Grignard reagent, and 3-hydroxy substituted acetals by reaction with alcohols, and as monomers for polymerization to polyoxyalkylene compounds employing, for example, trialkyl aluminum compounds with water in accordance with known processes.
