摘要：

A light hydrogenation process involving the dissolution of zinc dust in diluted formic acid was developed to study the early hydrogenation stages of [Li@C-60]+PF6- and C-60. The hydrogenation of the two substrates was followed through the electronic absorption spectroscopy and it was found that the metallofullerene reacts with hydrogen at least 2.4 times faster than C-60, in line with theoretical expectations which suggest that [Li@C-60] is a better free radical acceptor than C-60. The key absorption bands of the resulting fulleranes at low degree of hydrogen content were determined and discussed in an astrochemical perspective.
