Synthesis of Ar@C60 is described, using a route in which high-pressure argon filling of an open-fullerene and photochemical desulfinylation are the key steps for >95% encapsulation of the noble gas. Enrichment by recycling HPLC leads to quantitative incorporation of argon in the product endofullerene, with a mass recovery of tens of milligrams, allowing the first characterisation of fine structure in the solution 13C NMR spectrum.
描述了 Ar@C60 的合成，该方法的关键步骤是高压氩气填充开富勒烯和光化学脱硫，从而实现了 >95%的稀有气体封装。通过循环高效液相色谱法进行富集，导致氩气在产物内包 fullerene 中定量掺入，质量回收率达数十毫克，从而首次对溶液 13C NMR 谱中的精细结构进行了表征。
