Tellurium and selenium incorporated 5,10,15,20-meso-unsubstituted-21,23-ditellura/diselena core-modified porphyrinogens (N2Te2 and N2Se2), 5,10,15,20-meso-unsubstituted-21-tellura/selena core-modified porphyrinogens (N3Te and N3Se) and fully substituted meso-carbons porphyrinogens (N2Te2, N2Se2 and higher analogs) are synthesized by 3 + 1 condensation of tellurophene/selenophene dipyrranes and their
掺入碲和硒的5,10,15,20-内消旋未取代的21,23-二tellura / diselena核修饰的卟啉原(N 2 Te 2和N 2 Se 2),5,10,15,20-内消旋未取代的-21-tellura /塞莱娜芯改性卟啉原(N 3碲和N 3 SE)和完全取代的内消旋β-碳卟啉原(N 2特2,N 2硒2和更高的类似物)通过3 + 1缩合碲的合成/ BF 3-乙酸乙酯或BF 3存在下的亚硒二吡喃及其相应的二醇–甲醇。的内消旋-未被取代的和取代的卟啉原被氧化使用氯醌/ 0.1%含水的FeCl 3在CHCl 3在室温下,得到相应的卟吩和卟啉被进一步降低到相应的二氢卟酚和菌绿素,而完全内消旋取代的卟啉原被发现是Hg 2+的良好配体。通过IR,1 H,13 C,125 Te,77 Se NMR,CHN分析,质谱和单晶XRD表征产物的结构。
