(e.g., 4 and 5) linked through the 10-positions with phenyl linker units. Using a similar methodology, phenyl-linked corrole−porphyrin dyads 28 and 30 were also prepared. By way of intermediate phenyl-linked unsymmetrical bisdipyrromethanes, a completely unsymmetrical heterobimetallic bisporphyrin system, 45, was synthesized. Low-valent titanium coupling (McMurry) reactions were used to prepared stilbene-linked
描述了一系列对称和不对称双卟啉、双氯啉和双氯苯,以及具有乙烯、苯基和二苯乙烯连接单元的卟啉-二氢卟酚和卟啉-科尔二元组的逐步合成和表征。首先开发了通过α,c-双二烯盐1合成10-取代的corroles 2及其钴配合物9的方法,然后扩展以提供通过10位连接的双corroles(例如4和5)与苯基接头单元. 使用类似的方法,还制备了苯基连接的 corrole-卟啉二元组 28 和 30。通过中间体苯基连接的不对称双二吡咯甲烷,合成了完全不对称的异双金属双卟啉系统 45。低价钛偶联(McMurry)反应用于制备茋连接的双二吡咯甲烷(例如,46),随后将其转化为茋连接的双卟啉(例如,48)。含有 pf 的卟啉的 McMurry 交叉偶联反应...
