A meso‐aryl and β‐alkyl substituted sapphyrin and its rhodium(I) and silver complexes were synthesized. This sapphyrin was so stable that the non‐inverted and warped structure could be analyzed by X‐ray crystallography even in its neutral state. Its bis‐rhodium(I) complex has a more planar structure than the sapphyrin with enhanced aromaticity over the conjugation circuit. On the other hand, silver metalation of the sapphyrin caused a marked core rearrangement into a neo‐confused sapphyrin derivative with a C(α)−N bond and a twisted macrocycle.

稳定的中芳基β-烷基杂色沙弗林，具有扭曲的π共轭回路和新混淆的沙弗林-银（I）配合物

合成了一个介孔芳基和一个β烷基取代的血红素及其铑（I）和银配合物。该藤黄素非常稳定，即使在中性状态下，也可以通过X射线晶体学分析其非反转和翘曲的结构。它的双铑（I）络合物比角质素具有更平坦的结构，在共轭回路中具有增强的芳香性。另一方面，皂苷的银金属化导致显着的核重排成具有C（α）-N键和扭曲的大环的新混淆的皂苷衍生物。
