The structure of fullerene compounds
This account reviews fullerene chemistry research at Sussex. C 60Ph 2 and C 60Ph 4 have been isolated as minor products from the reaction of C 60Cl 6 with C 6H 6 and FeCl 3. [70]Fullerene reacts with ICl in C 6H 6 producing a single isomer of C 70Cl 10 in high yield. C 70Ph 8, which has a [5,6] cage...

9OH is isolated as a minor component of foregoing reaction mixtures. Autoxidation of C
70Ph
8 yields the bislactone, C

8 with anthracene, C
14H
10, in C
6H
6 produces C

10). Two new methanofullerenes, C
60(CBr
2), and C
60(CHCN), are produced by treating [60]fullerene in C
6H
6 with either CH
2BrCN or CHBr
2 in the presence of LDA. Reaction of [60]fullerene with alkyl buta-2,3-dienoates in the presence of a phosphine results in [3 + 2] cycloadditions which produce alkyl 3′H-1,2-([1′,2′]cyclopenta)[60]fullerene-5′-carboxylates. [60]Fullerene reacts with Pt(cod)
