Abstract

In contrast to octaethylporphyrin, which forms a very labile bis-BF₂ complex, treatment of the hexa- and octapyrrolic expanded porphyrins amethyrin and [32]octaphyrin with BF₃·OEt₂ under standard reaction and work-up conditions gives rise to stable, non-labile mono- and bis-BF₂ complexes; these were readily characterised by, inter alia, X-ray diffraction analyses.
