PROCESS FOR PREPARING 3-PHENOXY-BENZENE DERIVATIVES
摘要
3-Phenoxybenzene derivatives are prepared by a method which comprises the steps of(a) chlorinating benzaldehyde with chlorine gas in the presence of a hydrocarbon and a Lewis acid catalyst to obtain 3-chlorobenzaldehyde; (b) reacting the 3-chlorobenzaldehyde with ethylene glycol to obtain 2-(3-chlorophenyl)-1,3-dioxolane; (c) etherifying said dioxolane with an alkali phenolate to yield the intermediate 2-(3-phenoxyphenyl)-1,3-dioxolane and converting this intermediate to the corresponding aldehyde, cyanohydrin, sulfonic acid salt or oxime derivative.
