The interaction of stable 2-RSO2-benzonitrile oxides la--e (R = Ph, Bu t, or PhMeN) with C60 fullerene proceeds at the dovble (6,6)-bond of futlerene as tile [3+21 cycloaddition to form the corresponding isoxazolines 2a--c. The molecular structure of compound 2b was established by X-ray structural analysis. The interaction of C60 fullerene with 2-(5-methyl-4-nitrothiophene)carbonitrile sulfide, which was obtained by thermoiysis of 5-(5 "-methyl-4"-nitro-2 "-thienyl)-1,3,4-oxathiazol-2-one, affords only unstable products.
Aus der Titelverbindung (I) bildet sich unter der Einwirkung von Nukleophilen wie K‐tert.‐butylat neben einem 1,1‐Spirokomplex offenbar ein innermolekularer 1,2‐Komplex (II) (1H‐NMR‐, sichtbares Spektrum).

ChemInform Abstract The title compounds (IV) are prepared by a novel procedure starting from the known spirodithiolanes (I). The mechanism of the formation of the mercapto derivatives (II) is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
