The cationic [RuCl(η6-p-cymene)(HCNNa)]Cl (1a) (HCNNa = 1-(6-arylpyridin-2-yl)methanamine) and the neutral RuCl 2(η6-p-cymene)(HCNNb) (1b) (HCNN b = 2-aminomethylbenzo[h]quinoline) complexes have been obtained by reaction of the precursor [RuCl(μ-Cl)(η6-p-cymene)] 2 with the corresponding nitrogen ligand (HCNNa and HCNNb) in THF. Complex 1a reacts cleanly with monodentate (P = PPh3) and bidentate phosphines (PP = dppb, dppf) in ethanol in the presence of NEt3, affording the pincer catalysts RuCl(CNN a)(PPh3)2 (2) and RuCl(CNNa)(PP) (PP = dppb 3, dppf 4). Similarly, the benzo[h]quinoline pincer derivative RuCl(CNNb)(dppb) (5) is obtained from 1b and dppb. Complex 3 has also been prepared in a one-pot reaction from [RuCl(μ-Cl)(η6-p- cymene)]2, HCNNa, and dppb in ethanol. Similarly, the chiral complex RuCl(CNNa)((R,S)-Josiphos) was isolated as a single stereoisomer by treatment of [RuCl(μ-Cl)(η6-p-cymene)] 2 with HCNNa and (R,S)-Josiphos in 1-butanol. Reaction of 1a and 1b with dppb affords cymene diphosphine species by displacement of the HCCN ligand.

The ruthenium-p-cymene complexes [p-cymene)Ru(1,2,3,4-Me 4-NUPHOS)Cl][SbF6] and [(p-cymene)Ru(1,4-Et 2-2,3-cyclo-C6H8-NUPHO S)Cl][SbF6] were prepared by reaction of [(p-cymene)RuCl2/s
