摘要：
In accordance with the present invention, it has been discovered that arylpropargyl ethers can readily be isomerized to produce benzopyrans, by subjecting a defined group of aryl propargyl compounds to isomerization conditions in suitable solvent. Invention isomerization process allows the production of a good yield of a variety of benzopyran materials, free of contaminating diluent. Benzopyrans prepared in accordance with the present invention are useful for the preparation of adhesive compositions, microelectronic devices, and the like.
