with pyrrole and benzaldehyde afforded a mixture of porphyrins of general formula β-FnTPP (n=0,2,4,6,8) displaying linearly correlated spectroscopic and electrochemical properties. With the second synthon, condensation with benzaldehyde produced an unresolvable mixture of β-tetrafluoroporphyrins presenting spectroscopic and electrochemical properties in coherence with those observed in the first case
已经研究了使用Lindsey条件从3,4-二氟-1 H-吡咯或3-氟-1 H-吡咯开始合成部分β-氟化的内消旋-四苯基卟啉。在第一合成子的情况下,缩合与吡咯和苯甲醛,得到的通式β-F卟啉的混合物Ñ TPP(Ñ显示线性相关光谱和电化学性质= 0,2,4,6,8)。在第二个合成子中,与苯甲醛的缩合产生了不可分辨的β-四氟卟啉混合物,具有与在第一种情况下观察到的一致的光谱和电化学性质。初步,迄今未知的3-氟-1的合成与分离H-吡咯已经通过几种方法达到了。
