prepared via the condensation of o-quinones with diaminomaleodinitrile. Benzo[f]quinoxaline-2,3-dinitrile was obtained from 1,2-naphthoquinone, and a series of isomeric, di-tert-butyl substituted 5,6-(9,10-phenanthro)-2,3-dicyanopyrazines were prepared from the corresponding di-tert-butyl-9,10-phenanthrenequinones. Complexation of benzo[f]quinoxaline-2,3-dinitrile, and unsubstituted 5,6-(9,10-phenanthro)-2
通过邻醌与二氨基马来二腈的缩合制备了 2,3-二氰基吡嗪的几种衍生物。以 1,2-萘醌为原料制备了苯并[f]喹喔啉-2,3-二腈,以及一系列异构的二叔丁基取代的 5,6-(9,10-菲)-2,3-二氰基吡嗪由相应的二叔丁基-9,10-菲醌制备。苯并[f]喹喔啉-2,3-二腈和未取代的5,6-(9,10-菲)-2,3-二氰基吡嗪与合适的金属盐络合,生成四-2,3-(苯并[f]喹喔啉基)四氮杂卟啉和四-2,3-[5,6-(9,10-菲)]四氮杂卟啉。不含金属的四-2,3-[5,6-(9,10-菲并)四氮杂卟啉是通过在 HCl 中脱金属从二锂衍生物中获得的。这些化合物在有机溶剂中的溶解度有限,例如喹啉、并聚合在解决方案中。为了消除聚集现象并确定有角度退火的萘酞菁氮杂类似物的光谱特性,我们...
