PCl3 and POCl3 are the most important sources of phosphorus-containing compounds. They are also used for large-scale industrial productions. However, chemical reactions using the highly reactive PCl3 and POCl3 tend to result in overreactions. In a...
Construction of a 21‐Membered‐Ring Orifice on Fullerene
Von Wiley-VCH zur Verfügung gestellt
Open-fullerenes possessing a huge orifice with a ring-atom count exceeding 19 have been confined to only a few examples. Herein, we report a 20-membered-ring orifice which enables for a guest molecule such as H2, N2, and CH3OH to be encapsulated inside the fullerene cavity. In addition, a 21-membered-ring orifice was prepared via a reductive decarbonylation, in which one of the carbon atoms was moved out of the fullerene skeleton as an N,N-dimethylamide group. At a low temperature of –30 °C, an Ar atom was encapsulated with an occupation level up to 52%. At around room temperature, the amide group on the orifice rotates along with the C(amide)–C(fullerene) bond axis, realizing a self-inclusion of the methyl substituent on the amide group as confirmed NMR spectroscopically and computationally.Zum Volltext
