zirconium‐mediated double homologation method was successfully applied for the synthesis of multi‐substituted pentacene derivatives from 1,2,4,5‐tetrakis(propargyl)benzenes. The bis(zirconacyclopentadiene) intermediates were also characterized. Among these symmetrical derivatives, tetra‐ and octa‐substituted pentacenes undergo reversible conversion between monomeric and dimeric forms.
双重:锆介导的双重同源方法已成功用于从1,2,4,5-四(炔丙基)苯合成多取代并五苯衍生物。还对了双(锆碳环戊二烯)中间体进行了表征。在这些对称衍生物中,四和八取代的戊烯在单体和二聚体形式之间进行可逆转化。
