Synthesis of optically pure [60]fullerene e,e,e-tris adducts

摘要

The reaction of readily available optically active Si-tethered tris(malonates) with C_(60) gave easily separable diastereoisomers differing by the absolute configuration of the inherently chiral addition pattern on the fullerene core. The absolute configuration of the e,e,e addition pattern has been unambiguously determined using X-ray crystal structure analysis.
