资源简介:

The synthesis of an inverted, methoxylated sapphyrin derivative is described. This system, wherein inversion of pyrrolic nitrogen atoms is configurationally enforced via the use of a 3,3‘-bipyrrolic precursor, displays what is best described as “weak aromaticity” as judged from its spectroscopic features and supporting theoretical calculations.
