Das Arenologieprinzip und erste präparative Anwendungen

Abstract

According to the principle of arenology, functional groups of organic chemistry such as –O–H, –S–H, –CO–X, –CS–X, etc. are end links of homologous series whose higher links (“6π-, 10π-electron stage”, etc.) are being formed by “areno-functional groups” (nucleo- and electrophilic hetaryl residues with suitable substitutents). Since the higher links resemble the end links in essential conditions, it is reasonable to “transpose” organic compounds with functional groups into higher π-electron stages. — The classic functional groups can sometimes be found directly linked in organic compounds without residues sticking to them (p.e. H₂N–CO–NH₂, H₂N–CO–CO–NH₂); most times, however, they are found as appendix to chains of carbon atoms (open or cyclic) or as binding links between such chains. Transposing into the 6π- or 10π-electron stage leads to combinations of nucleo- and electrophilic heterocyclic arenes (= polyarenes) in the first case, whereas in the second case transposing leads to hetaryl alkanes, protophanes and phanes. Syntheses of such compounds and their conditions, induced by the principle of arenology, are being described.
