Facile purification of C60O-containing [60]fullerene using trialkylphosphines at room temperature

A novel method using trialkylphosphines is reported for the facile purification of [60]fullerene containing C60O. When tri-n-butylphosphine and tri-n-octylphosphine were added to unrefined C 60 (ca. 97% purity) in 1,2,4-trimethylbenzene, C60O was readily reduced to give high-purity C60 (>99% purity). The best results were obtained for a high concentration (>1.0 wt %) of unrefined fullerene treated with tri-n-octylphosphine at room temperature. This method is simple and fast in comparison with conventional alumina chromatography, and thus, it is well-suited to industrial-scale separation.

Treatment of a dicopper(I,I) complex with nitric oxide produces a dicopper μ-oxo, μ-nitrosyl complex [LCu2(μ-O)(μ-NO)]2+, representing the first structurally characterized μ-oxo, μ-nitrosyl metal complex. This compound can also be synthesized from the reaction of nitrite with an [LCuIICuI]3+ synthon. Full characterization of the thermal-sensitive [LCu2(μ-O)(μ-NO)]2+ complex with IR, EPR, and X-ray crystallography suggests a localized mixed-valent CuIII, CuII, O2?, NO? formulation. The [Cu2(μ-O)(μ-NO)]2+ core efficiently oxidizes exogenous substrates, such as phosphine, cyclohexadienes, and isochroman to afford phosphine oxide, benzene, and 1-isochromanone. Since both nitrite and nitric oxide are proposed oxidants in denitrifying methane oxidation, the oxidative reactivity of [Cu2(μ-O)(μ-NO)]2+ core is potentially relevant to anaerobic methane oxidation observed in methanotro hic archaea

The Trityl-Cation Mediated Phosphine Oxides Reduction
Landais, Yannick,Laye, Claire,Lusseau, Jonathan,Robert, Frédéric
supporting information, p. 3035 - 3043 (2021/05/10)
Reduction of phosphine oxides into the corresponding phosphines using PhSiH3 as a reducing agent and Ph3C+[B(C6F5)4]? as an initiator is described. The process is highly efficient, reducing a broad range of secondary and tertiary alkyl and arylphosphines, bearing various functional groups in generally good yields. The reaction is believed to proceed through the generation of a silyl cation, which reaction with the phosphine oxide provides a phosphonium salt, further reduced by the silane to afford the desired phosphine along with siloxanes.
