Synthesis and Reactions of Organoplatinum Compounds of C60, C60Ptn

Abstract The organoplatinum compound of C60, C60Ptn (n = 1–2), was prepared either by the reaction of C60 with Pt(dba)2 or by the thermal disproportionation of C60Ptn (n = ca. 1). The C60Ptn obtained catalyzed the hydrogenation of diphenylacetylene regardless of the platinum content. Cleavage of carbon-platinum bonds of C60Ptn (n = ca. 1) was accomplished by the reactions with phosphines or phosphites, which provided general access to (η2-C60)PtL2 [L = phosphines and phosphites].
