Photochemical site-selective synthesis of [70]methanofullerenes

Methanofullerenes such as the well-known [70]PCBM are commonly synthesized under harsh conditions to obtain the product as a mixture of site-isomers (namely a, b and minor c) due to the D5h symmetry of the C70 cage. We report the first site-selective synthesis of [70]methanofullerenes under light ir...
