Matsuo, Yutaka Mitani, Yuichi Zhong, Yu-Wu Nakamura, Eiichi Remote Chirality Transfer within a Coordination Sphere by the Use of a Ligand Possessing a Concave Cavity The possibility to enhance the effect of a modest chiral element in a metal ligand by the use of a second ligand possessing a concave cavity has been examined for the examples of 1,3- and 1,4-chirality transfer within the metal coordination sphere. 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. propho;Concave Cavity;chiral element;Coordination Sphere;diastereoselectivity;Remote Chirality Transfer;metal coordination sphere;cationic complexes;Ligand Possessing;metal ligand;NC;CO;t BuCN;Cl;Ru;chirality transfer 2006-05-22
