Complexation of Ru(C<sub>60</sub>Me<sub>5</sub>)Cl(CO)<sub>2</sub> with (<i>R</i>)-prophos [(<i>R</i>)-1,2-bis(diphenylphosphino)propane] took place with excellent diastereoselectivity to give a configurationally stable chiral-at-metal complex, Ru(C<sub>60</sub>Me<sub>5</sub>)Cl((<i>R</i>)-prophos). This complex was converted, with good to perfect diastereoselectivity, into a variety of cationic complexes, [Ru(C<sub>60</sub>Me<sub>5</sub>)((<i>R</i>)-prophos)L][SbF<sub>6</sub>] (L = MeCN, <i><sup>t</sup></i><sup></sup>BuCN, methacrolein, acetone, CO, BnNC, 2,6-Me<sub>2</sub>C<sub>6</sub>H<sub>3</sub>NC), and a vinylidene complex, [Ru(C<sub>60</sub>Me<sub>5</sub>)(CCPhH)((<i>R</i>)-prophos)][SbF<sub>6</sub>]. The chirality transfer to the reactants reacting in the outer sphere of the coordination resulted in an asymmetric Diels−Alder reaction, albeit with modest selectivity.
