Preparation of alkoxy halides.

摘要

Alkyl-, aryl- or alkylaryl-alkoxy halides are prepared by reacting the corresponding alkoxy alcohol with a halogenating agent, e.g., thionyl chloride, in the presence of an amide as catalyst. In addition to being faster, the catalysed reaction results in an increased yield of desired product and a decrease in the tendency of the polyoxyalkylene chain to cleave.
