Diquinoline Oxideの合成研究 (第4報)

抄録

By the respective condensation of 5-bromoquinoline with 6-, 7-, and 8-hydroxyquinoline, in the presence of copper dust, diquinoline 5, 6′-oxide (I), 5, 7′-oxide (II), and 5, 8′-oxide (III) were prepared. Condensation of 7-bromoquinoline and 5-hydroxyquinoline under the same reaction conditions afforded (II). A few derivatives of these diquinoline oxides were also prepared.
