title: Activation of open-cage fullerenes with ruthenium carbonyl clusters.
abstract: Reactions of the open-cage fullerene C63NO2(Py)(Ph)2 (1) with [Ru3(CO)12] produce [Ru3(CO)8(μ,η(5)-C63NO2(Py)(Ph)2)] (2), [Ru2H(CO)3(μ,η(7)-C63N(Py)(Ph)(C6H4))] (3), and [Ru(CO)(Py)2(η(3)-C63NO2(Py)(Ph)2)] (4), in which the orifice sizes are modified from 12 to 8, 11, and 15-membered ring, through ruthenium-mediated C-O and C-C bond activation and formation.
