developed for photodehydrocyclization of stilbenes for the synthesis of phenanthrenes and helicenes. This procedure involves the use of THF as a scavenger of hydriodic acid produced during iodine mediated photodehydrocyclization. The use of THF is advantageous due to its higher boiling point, lower cost and easy availability as compared to propylene oxide. The method is applied to synthesize a number
已开发出一种用于合成菲和螺旋烯的二苯乙烯光脱氢环化的改进程序。该过程涉及使用 THF 作为碘介导的光脱氢环化过程中产生的氢碘酸的清除剂。由于与环氧丙烷相比,THF的沸点更高、成本更低且易于获得,因此使用THF是有利的。该方法用于合成多种菲和螺旋。
