Abstract

A novel method for the preparation of dibenzoxanthene was described. The reaction of 2-naphthols with an allylic alcohol in the presence of a bismuth triflate catalyst under air gave the corresponding dibenzoxanthenes in good yields. The reaction intermediates and reaction pathways in the bismuth-catalyzed reaction of 2-naphthol with 2-methylprop-2-en-1-ol were determined by ¹H-NMR analysis. Under similar reaction conditions, 2-naphthol was reacted with various aldehydes to afford the corresponding dibenzoxanthenes in good yields.

制备二苯并氧杂蒽的新方法；2-萘酚与烯丙基醇在三氟化铋催化剂作用下的反应

介绍了一种制备二苯并氧蒽的新方法。在三酸铋催化剂存在下，在空气中使 2-萘酚与烯丙醇反应，可以得到相应的二苯并氧蒽，而且产率很高。通过 1H-NMR 分析确定了铋催化的 2-萘酚与 2-甲基丙-2-烯-1-醇反应的反应中间产物和反应途径。在类似的反应条件下，2-萘酚与不同的醛类发生反应，得到相应的二苯并氧蒽，收率良好。
