This review underscores the conformational flexibility of porphyrinoids, a unique class of
functional molecules, starting from the smallest triphyrins (1.1. 1) via [18] porphyrins (1.1 …

The replacement of one or more pyrrolic building block (s) of a porphyrin by a nonpyrrolic
heterocycle leads to the formation of so-called pyrrole-modified porphyrins (PMPs) …

The activation of C—C bonds is of fundamental interest in the construction of complex
molecules from petrochemical feedstocks. In the case of the archetypal aromatic …

The world of modified porphyrins changed forever when an N-confused porphyrin (NCP), a
porphyrin isomer, was first published in 1994. The replacement of one inner nitrogen with a …

Following immediately after the serendipitous discovery of N-confused porphyrins,
remarkably diverse carbaporphyrinoid systems have been synthesized and investigated. By …

Core alteration, affording heteroporphyrinoids and carbaporphyrinoids, allows for the
exploration of porphyrin-like or porphyrin-unlike coordination chemistry. Such a strategy has …

The cleavage of carbon− carbon (C− C) bonds by transition metals is of great interest,
especially as this transformation can be used to produce fuels and other industrially …

Cyclization of a pentapyrrane with two terminal β-linked pyrroles afforded a
dihydrosapphyrin isomer (1) with the pyrroles linked in a unique β, α–α, β mode, which was …

Benziporphyrins were first discovered over 20 years ago. Although initially they were
considered to be a chemical curiosity, a wide range of benzene-containing porphyrinoid …

The cavities of carbaporphyrinoid systems provide unique environments for the formation of
organometallic species. These systems commonly act as either dianionic or trianionic …
