We report an improved synthesis of cis-[Ru(CH3CN) 2((1-3-n)-C3H5)((1,2:5,6-n)-C8H 12)]BF4 and its use in the synthesis of [Ru(bisphosphine)((1-3:5,6-n)-C8H11/sub

Simple and efficient: Protonation of [Ru(1,2:5,6-η-cod)(η6-cot)] (cod = 1.5-cyclooctadiene, cot = 1,3,5-cyclooctatriene) with HBF4 · Et2O and then reaction with chiral bisphosphane legands (P P = Me-DuPHOS, BINAP, Tol-BINAP, JOSIPHOS) afford the corresponding [Ru(P P)(H)(η6-cot)]+ or [Ru(P P)(1,2,3,4,5-η-C8H11′)]+ (C8H11′ = 2,4-cyclooctadienyl; see scheme). Exposure of these cations to H2 in solvents (sol) such as acetone, methanol, and THF affords [Ru(P P)-(H)(sol)3]+, which are catalysts for (amongst other things) enantioselective hydorgenations of alkenes.
