Synthesis, Structure, and Reactivity of [RuCl(PP)L]PF6 (PP = (PPh3)2, Ph2P(CH2)4PPh2; L = P(py)3, PPh(py)2, py = 2-pyridyl). the Missing P,N,N'-Coordination Mode for 2-Pyridylphosphines

The complexes [RuCl(PPh3)2(P,N,N'-PPh3-x(py) x)]PF6 (x = 2, 1b; 3, lc; py = 2-pyridyl) were isolated from the reaction of RuCl2(PPh3)3 with 1 equiv of PPh3-x(py)x and NH4PF6 in acetone. Crystals of 1b (C52H43C1F6N2P4Ru) are monoclinic, a = 17.795(2), b = 11.375(4), and c = 23.343(2) A, β= 97.012(8)°, Z = 4, space group P21/c; those for le (C51H42ClF6N3P4Ru) are monoclinic, a = 17.812(1), b = 11.353(2), and c = 23.391(1) A, β = 97.738(5)°, Z = 4, space group P21/c. The isomorphous structures were solved by the Patterson method and were refined by full-matrix least-squares procedures to R = 0.036 and 0.033 (RW = 0.035 and 0.031) for 7690 and 8121 reflections with I ≥ 3σ(I), respectively. The P,N,N'-coordination mode for 2-pyridylphosphines is previously unreported. The P,N-coordinated complexes cis-RuCl2(dppb)(PPh3-x(py)x) (x = 1-3; dppb = Ph2P(CH2)4PPh2) were made by isomerization of the corresponding trans-dichloro isomers, which are themselves synthesized from RuCl2(dppb)(PPh3). The cis complexes in CHCl3 or CH2C12 dissociate chloride reversibly with formation of P,N,N'-coordinated PPh3-x(py)x species, which were isolated as [RuCl(dppb)(PPh3-x(py)x]PF6 (x = 2, 3). Reactions of CO with the species containing the strained P,N,N'-coordination mode lead to displacement of a coordinated pyridyl and formation of the P,N-coordinated complexes [RuCl(CO)(PP)(PPh3-x(py)x)]PF6 (PP = (PPh3)2, x = 2, 3; and PP = dppb, x = 2, 3). The CO reactions are partially reversible. Solution structures of the complexes were determined by NMR, IR, and UV-visible spectroscopies and conductivity.

Synthesis, characterization, and reactivity of a ruthenium(II) N,N′,N″-tris(2-pyridyl)phosphine complex. X-ray analysis of RuCl2(PPh3)(Ppy3) (py = 2-pyridyl)

Reaction of RuCl2(PPh3)3 with Ppy3 (py = 2-pyridyl) in benzene produced the N,N′,N″-Ppy3 complex RuCl2(PPh3)(PPy3) 1. Crystals of RuCl2(PPh3)(Ppy3). 2CH2Cl2(C35H31Cl6N 3P2Ru) are monoclinic, a = 17.269(2), b = 10.797(1), c = 20.604(1) A, β = 107.461(6)°, Z = 4, space group P21/c. The structure was solved by the Patterson method and was refined by full-matrix least-squares procedures to R = 0.039 and Rw = 0.035 for 4184 reflections with I ≥ 3σ(I). Complex 1 reacts in MeOH or benzene with two-electron donors (L) to give the chloride-substituted, [RuCl(L)(PPh3)(Ppy3)]PF6, or the triphenyl-phosphine-substituted products, RuCl2(L)(Ppy3), (L = CO, MeCN, PhCN), respectively. [RuCl(MeOH)(PPh3)(Ppy3)]BPh4 was also isolated. The non-coordinated phosphorus atom in 1 was oxidized to form RuCl2(PPh3)(OPpy3).
