PROCESS FOR PREPARING HYDROXYBENZOCYCLOBUTENES |
摘要 |
A process for preparing a 3- or 4-hydroxybenzocyclobutene comprises reacting a 3- or 4-halogenzocyclobutene reactant with an alkali metal hydroxide by heating in an aqueous alcohol medium at a temperature from about 50 DEG C. to a temperature at which dimerization or oligomerization of a benzocyclobutene reactant or product is a significant side reaction, in the presence of a metal-containing catalyst, for a time sufficient to convert the halobenzocyclobutene reactant to the hydroxybenzocyclobutene product.
