leads, after treatment with aqueous sodium fluoride, to the expected functionalized (E)-α,β-unsaturated carboxylic acids 3 in a stereoselective manner. The probable reaction mechanism involves free radical intermediates.
A method for selective production of ε-caprolactam, wherein a substance inducible from a biomass resource is used as a material; the reaction process is short; ammonium sulfate is not produced as a by-product; and production of by-products is suppressed; is disclosed. The method for producing ε-caprolactam comprises the step of reacting a particular compound inducible from a biomass resource, such as α-hydromuconic acid, 3-hydroxyadipic acid, or 3-hydroxyadipic acid-3,6-lactone, or a salt thereof with hydrogen or ammonia.
