Functional phosphines XV. Ruthenium complexes containing C5H8(PR2)2 and Ph2PCH2CR2′NH2 ligands (R = Me, Ph, OPh; R′ = H, Me): synthesis and application to homogeneous CO hydrogenation and transfer hydrogenation

Treatment of [Ru(η4-C8H12){η3-(CH2)2CMe}2] with C2 chiral cyclopentane-1,2-diyl-bis(phosphines) trans-1,2-C5H8(PR2)2 in hexane afforded the chelate complexes [Ru{η3-(CH2)2CMe}2{1,2-C5H8(PR2)2}], where R = Me (2), Ph (3), NC5H10 (4), and OPh (5).
