Regioselective preparation of a bis-pyrazolinofullerene by a macrocyclization reaction. | LitMetric

Regioselective preparation of a bis-pyrazolinofullerene by a macrocyclization reaction.

Chem Commun (Camb)

Universidad de Castilla la Mancha, Instituto de Nanociencia, Nanotecnología y Materiales Moleculares (INAMOL), 45071-Toledo, Spain.

Published: November 2016

A single isomer of a pyrazolinofullerene bis-adduct was prepared by tether-directed remote functionalization. Specifically, a macrocyclization reaction between C and a bis-hydrazone reagent has been carried out to generate a regioisomerically pure fullerene bis-adduct which presents a lower LUMO than pristine C.
