“…Beginning with spherical fullerenes, expansion of the aromatic surface of carbon allotropes leads to SWCNTs and MWCNTs. Further expansion by unrolling nanotubes into infinite sheets leads to graphene 75 as formal homolog of SWCNTs 2 and graphite 76 as formal homolog of MWCNTs 3 (Figure 10) [112,[114][115][116][117][118][119][120][121][122][123]. Graphite is the oldest, most common carbon allotrope composed of sp 2 hybridized atoms, complementary to diamond as the archetypal sp 3 carbon allotrope.…”

Anion–π catalysis, introduced in 2013, stands for the stabilization of anionic transition states on π-acidic aromatic surfaces. Anion–π catalysis on carbon allotropes is particularly attractive because high polarizability promises access to really strong anion–π interactions. With these expectations, anion–π catalysis on fullerenes has been introduced in 2017, followed by carbon nanotubes in 2019. Consistent with expectations from theory, anion–π catalysis on carbon allotropes generally increases with polarizability. Realized examples reach from enolate addition chemistry to asymmetric Diels–Alder reactions and autocatalytic ether cyclizations. Currently, anion–π catalysis on carbon allotropes gains momentum because the combination with electric-field-assisted catalysis promises transformative impact on organic synthesis.
