Abstract
[7H]Benzanthrene 2 was used as a catalyst for the transfer hydrogenati on of C60 and C70 by 9,10-dihydroanthracene 1. The catalyst allowed mi lder reaction conditions (250-degrees-C) than the non catalyzed proced ure did (350-degrees-C).2 The reaction products identified by EI-MS we re C60H36, C60H44 and C70H36 thus a higher degree of hydrogenation cou ld be reached in the case of C60. The method is also suitable for deut eration. A structure proposal for C70H36 and its DELTAH(f)(g) from mol ecular mechanics calculations are presented.
