ChemInform Abstract
In the reaction of phenacyl bromide (III) and the benzodioxin (I) which equilibrates with the pyrocatechol ether (II), the benzodioxepine E-(IV) is the only reaction product. Acetylation of E-(IV) gives the acetate E-(VI). (X-ray data of E-(IV): triclinic, space group P1, Z=2; E-(VI): rhombic, space group Pbca, Z=16).
