Construction of fullerocyclobutene derivatives through copper(I)-mediated radical annulation of C60Cl6 with aryl acetylenes.
Have a radical ball! Reaction of C(60)Cl(6) with aryl acetylenes through a copper(I)-mediated annulation route to form fullerocyclobutene derivatives is reported. The fullerocyclobutenes are obtained in 36-53% yields and a possible radical mechanism is proposed for this novel reaction.
