coupling of [60]fullerene with N-sulfonylaldimines to afford novel 1,2hydrobenzylated [60]fullerene derivatives. We found that both group VIIB metals (cobalt, rhodium, iridium) and group VIIIB metals (nickel, palladium, platinum) perform this coupling reaction. A control experiment in the absence of aldimines produced C60H2, which showed that the reaction might proceed via a [60]fullerene metal complex

visible-light-promoted deoxygenative alkylation of imines with alcohols assisted by carbon disulfide and tricyclohexylphosphine. The key to success of this method is the activation of alcohols upon the formation and direct photoexcitation of xanthate anions. This one-pot protocol enables the selective C–O bond homolysis of diverse primary, secondary and tertiaryalcohols to react with a variety of N-sulfonyl and N-aryl
