2-溴[5]螺烯衍生物和取代的[7]螺烯已通过依赖于Heck型和光环脱氢反应的合成顺序制备。该程序为螺旋烯衍生物提供了一种新的、通用的和有效的方法，((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, 德国, 2004)
2-Bromo[5]helicene derivatives and substituted [7]helicenes have been prepared through a synthetic sequence relying on Heck-type and photocyclodehydrogenation reactions. This procedure provides a new, versatile and efficient approach to helicene derivatives, ((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
