Azaindenocorannulenes: Synthesis, Properties, and Chirality

By Xiaoqi Tian, Loïc Roch, Nicolas Vanthuyne, Jun Xu, Kim Baldridge and Jay Siegel

Abstract

International audiencePalladium-catalyzed intramolecular arylation provides bowl-shaped azaindenocorannulenes 7−9. Crystals of 8 show bowl-in-bowl columnar stacking. A substituent model rationalizes the first reduction potential of 18 related molecular bowls. The absolute configurations of bowls 7 and 9 are correlated with VCD and ECD spectra. The bowl inversion barrier of 9 (>190 kJ/mol) shows it to be more inert configurationally than chiral biaryl, phosphenes, or [n]helicenes
