The addition of nitrile oxides to [60] fullerene, leading to isoxazolinofullerenes, can be reversed using reducing agents such as Mo (CO) 6 or DIBALH. Thus, this reaction can be used, in principle, for protection/deprotection of [60] fullerene or for solubilization purposes. The tether-controlled tandem addition of nitrile oxides and azomethine ylides provides mainly cis-1 patterns. The determination of the structure of bisadducts was obtained by ...
