Recently many endohedral metallofullerenes such as M@C{sub 74}, M@C{sub 80}, and M@C{sub 82} (M: metal atom) have been successfully isolated by the high performance liquid chromatography (HPLC) technique. Some M@C{sub 60} were prepared in primary soots by an arc-heating or a laser-vaporization method, but the isolation of M@C{sub 60} has not yet been achieved because of the difficulties in extraction; only the extraction of Ca@C{sub 60} with pyridine has been reported as for. Recently we found that aniline is a suitable extraction solvent for Ca@C{sub 60} and Sr@C{sub 60}. For the isolation of M@C{sub 60} by an HPLC technique it is important to find a suitable extraction solvent for M@C{sub 60}. In the present study, we report the successful extraction of Y@C{sub 60}, Ba@C{sub 60}, La@C{sub 60}, Ce@C{sub 60}, Pr@C{sub 60}, Nd@C{sub 60}, and Gd@C{sub 60} with aniline under an air atmosphere. 14 refs., 2 figs.
