“…Similar results were obtained when the reaction was carried out with cobalt(II) chloride hexahydrate in refluxing acetonitrile–toluene. Cobalt(II) has previously been shown to direct the air oxidation of alkenes and in this case appears to promote the regioselective oxidation of azuliporphyrins . Azuliporphyrin 253a reacted similarly but afforded a lower yield (10%) of oxidation product 315a .…”

Following immediately after the serendipitous discovery of N-confused porphyrins, remarkably diverse carbaporphyrinoid systems have been synthesized and investigated. By replacing a pyrrolic unit within the porphyrin framework with cyclopentadiene, indene, azulene, cycloheptatriene, or benzene, new families of porphyrin-like macrocycles were produced. True carbaporphyrins are fully aromatic structures, while benziporphyrins are essentially devoid of macrocyclic aromatic character, and azuliporphyrins fall midway between the two extremes. Monocarbaporphyrinoids are superior organometallic ligands and form stable complexes with copper(III), silver(III), gold(III), nickel(II), palladium(II), platinum(II), rhodium(III), iridium(III), and ruthenium(II). Unusual oxidation reactions have also been discovered, commonly leading to derivatization of the internal carbon atom. In addition, structural rearrangements have been uncovered that allow the conversion of azuliporphyrins into benzocarbaporphyrins, and benziporphyrins into carbaporphyrins. Although less well studied, many examples of dicarbaporphyrinoids have been reported, and these show equally intriguing characteristics. Furthermore, contracted and expanded carbaporphyrinoids have been investigated. Studies in this area provide fundamental insights into the aromatic properties, tautomerization, and reactivity of porphyrins and related macrocyclic systems.

Die exakte atomare Architektur des katalytisch aktiven Zentrums steht im Zentrum des hier vorgestellten Ansatzes zum Design von Feststoffkatalysatoren. Er lieferte eine große Bandbreite neuartiger Katalysatoren unter anderem für regioselektive, formselektive und enantioselektive Reaktionen, für die effiziente Isomerisierung und Hydrierung von Alkenen sowie für die Oxidation von Alkanen an den endständigen Positionen. Bei allen Katalysatoren handelt es sich um mikroporöse oder mesoporöse Festkörper, deren Vorteile eine hohe spezifische Oberfläche und die Möglichkeit, feine Veränderungen in der Struktur und der Zusammensetzung durchzuführen, sind.
