, stands for the stabilization of anionic transition states on π-acidic aromatic surfaces. Anion–π catalysis on carbonallotropes 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 carbonallotropes 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 carbonallotropes gains momentum because the combination with electric-field-assisted catalysis promises transformative impact on organic synthesis.

Keywords: carbonallotropes; carbon nanomaterials; carbon-rich molecules; The era of carbon nanomaterials has started with the first reports on fullerenes and related compounds in the mid-eighties, and a tremendous increase of the research activity in the field has been observed ever since. New classes of
involving materials science, organic chemistry and physics.
Synthetic organic chemistry is a major part of carbon materials chemistry as the rational synthesis of carbonallotropes such as fullerenes and nanotubes and related molecular compounds with and without heteroatoms remains a challenging task. The
