Patent number: 4552855Abstract: Zeolite-metal catalysts having a substantial amount of catalytically active metal, e.g. iron, deposited in the cavities of the zeolite in zero-valent, small cluster form, are prepared by vaporizing the metal under low vapor pressure conditions in the vicinity of an organic liquid solvent, e.g. toluene, such that the metal dissolves in the solvent as a labile solvated zero-valent metal complex. This complex is contacted with the zeolite so that the complex diffuses into the cavities of the zeolite. Upon subsequent warming the solvated metal complex decomposes, leaving zero-valent small metal clusters in the zeolite cavities.Type: GrantFiled: November 30, 1983Date of Patent: November 12, 1985Inventors: Geoffrey A. Ozin, Linda F. Nazar, Francois Hugues

Patent number: 4533651Abstract: Catalyst systems for the oligomerization and/or isomerization of olefins which comprise a nickel (II) complex and a co-catalyst. The nickel (II) complex is a square planar species with a trivalent Group V donor ligand, preferably a phosphine or phosphite ligand, a halogen or pseudo-halogen ligand and a bidentate dithio ligand, especially a substituted dithio-.beta.-diketone ligand.Type: GrantFiled: October 17, 1983Date of Patent: August 6, 1985Assignee: Commonwealth Scientific and Industrial Research OrganizationInventors: Anthony F. Masters, Kingsley J. Cavell
