New high-yielding synthetic routes to the small-molecule endofullerenes H2O@C60, D2O@C60 and H2@C60 are described. The use of high temperatures and pressures for the endohedral molecule incorporation are avoided. A new partial closure step using PPh3, and final suturing using a novel Diels-Alder/retro-Diels-Alder sequence are amongst the advances reported.
本文描述了小分子内嵌富勒烯H2O@C60、D2O@C60和H2@C60的新型高产率合成路线。避免了使用高温高压来引入内嵌分子。所报道的进展包括使用三苯基膦（PPh3）的新的部分封闭步骤，以及使用新颖的狄尔斯-阿尔德/逆狄尔斯-阿尔德序列的最终缝合步骤。
