  Complexes of cobalt and nickel with tridentate ligand PNHP R are effective for hydrogenation of unsaturated compounds. Cobalt complex [(PNHP Cy )Co(CH 2 SiMe 3 )]BAr F 4 (PNHP Cy =bis[2-(dicyclohexylphosphino)ethyl]amine, BAr F 4 =B(3,5-(CF 3 ) 2 C 6 H 3 ) 4 )) was prepared and used with hydrogen for hydrogenation of alkenes, aldehydes, ketones, and imines under mild conditions (25-60° C., 1-4 atm H 2 ). Nickel complex [(PNHP Cy )Ni(H)]BPh 4 was used for hydrogenation of styrene and 1-octene under mild conditions. (PNP Cy )Ni(H) was used for hydrogenating alkenes.

  Methods and systems are provided for converting methane in a feed stream to acetylene. The method includes the further conversion of the acetylene to a hydrocarbon stream having propylene. The hydrocarbon stream is introduced into a supersonic reactor and pyrolyzed to convert at least a portion of the methane to acetylene. The reactor effluent stream is treated to convert acetylene to another hydrocarbon, and in particular olefins. The method according to certain aspects includes controlling the level of contaminants in the hydrocarbon stream.

  A series of polynuclear gold(I) sulfido complexes of bis(diphenylphosphino)amine ligands has been synthesized and characterized. A rather small variation in the conformation of the bis(diphenylphosphino)amine ligands has led to distinct differences in the identity of the polynuclear gold(I) sulfido complexes formed. Unprecedented concentration-dependent and solvation-dependent reversible cluster-to-cluster
