Résumé
To address the question of the role of chirality at the metal in enantioselective catalysis, a pseudo-tetrahedral three-legged piano-stool complex was prepd., i.e. [RuCl(C26H27N2P)](CF3SO3). Crystallog. data are given. Anchoring a phosphine and a pyrazole tether to an arene (PArN) yields, after ?6:?1:?1 coordination to Ru, [{?6:?1:?1-(PArN)}RuCl]+ as a 1:1 mixt. of enantiomers. Unfortunately, all attempts to resolve the enantiomers failed. The structure soln. revealed racemic crystals. [on SciFinder(R)]
