Cleavage reaction of 1, 6-dimethyldibenzo-p-dioxin (I) with metallic sodium in liquid ammonia gives two kinds of phenolic compound, one of which was found to be 2-hydroxy-3-methylphenyl o-tolyl ether (II) and the other, 2-hydroxy-6-methyl-phenyl m-tolyl ether (III).
Cleavage reaction of 1, 6-dimethoxy-3, 8-dimethyldibenzo-p-dioxin (VIII) with sodium in liquid ammonia, in the presence of sodium hydride, was found to inhibit the formation of the abnormal product, biphenyl derivative.
Summarizing the results obtained to date, some considerations were made on the reaction conditions and mechanism of cleavage reaction of dibenzo-p-dioxin derivatives with sodium in liquid ammonia.
