WebApr 21, 2024 · Spiropyran-containing methanofullerenes able to rapidly and reversibly respond to optical and chemical stimuli were synthesized for the first time by the Bingel–Hirsch reaction and catalytic cycloaddition of diazo compounds to carbon clusters. The effects of substituent structure in the new hybrid molecule and the WebThe Bingel‐Hirsch reaction of M3N@Ih‐C80 cations occurred via an unusual outer‐sphere single‐electron transfer (SET) process from the diethyl bromomalonate anion to the stable intermediate [M3N@C80(C2H5COO)2CBr]•. Remarkably, the diethyl bromomalonate anion was found to act as both a nucleophile and an electron donor.

WebThe chemical properties of a prototypical labile mono-EMF, Y@ Cs (6)-C 82, have been systematically disclosed for the first time via a Bingel–Hirsch reaction. Three mono-adduct isomers, namely, 2a, 2b and 2c out of 44 possibilities for the Y@ Cs (6)-C 82 cage have been readily isolated, demonstrating surprisingly high regioselectivity.
