Regioselective one-step synthesis of trans-3,trans-3,trans-3 and e,e,e [60]fullerene tris-adducts directed by a C3-symmetrical cyclotriveratrylene tether

The first covalent cyclotriveratrylene (CTV)–C60 adducts were prepared by the tether-directed Bingel reaction, which gave the two C3-symmetrical trans-3,trans-3,trans-3 and e,e,e tris-adducts with a high degree of regioselectivity.
