    Abstract: Gold (I) hydroxide complexes of the form Z—Au—OH and digold complexes of the form Z—Au-(μOH)—Au—Z where groups Z are two electron donors are provided. The groups Z may be carbenes, for example nitrogen containing heterocyclic carbenes (NHCs), phosphines or phosphites. The complexes can be used as catalysts, for example in reactions such as hydration of nitriles, skeletal arrangement of enynes, alkoxycyclization of enynes, alkyne hydration, the Meyer-Shuster reaction, 3,3′ rearrangement of allylic acetates, cyclization of propargylic acetates, Beckman rearrangements and hydroamination. The complexes can be used in medicine, for example in the treatment of cancer.

    Abstract: The invention concerns an organometallic compound of formula RO-M(L1)X (L2)Y (L3)Z wherein M is a metal selected from titanium, zirconium, hafnium, iron (III), cobalt (III) or aluminium; L1 and L2 are each independently selected from a diketonate, an ester or amide of acetoacetic acid, a hydroxycarboxylic acid or ester thereof, R1COO— where R1 is substituted or unsubstituted C5-C30 branched or linear alkyl, substituted or unsubstituted aryl including polycyclic structures such as naphthyl or anthracyl, phosphate, phosphinate, phosphonate, siloxy or sulphonato, provided that when L1 is a ligand which forms two covalent bonds with the metal atom, and x=1 then y=0; L3 is selected from substituted or unsubstituted aryloxy, R2COO— where R2 is a linear or branched C6-C30 alkyl or a substituted or unsubstituted aryl, a polyoxyalkyl or hydroxyalkoxyalkylgroup; R is alkyl or hydroxy-alkyl hydroxyalkoxyalkyl, or (hydroxy)polyoxyalkyl group, x, y and z are each either 0 or 1 (x+y+z)≦V−1, where V=the valency of the metal M. The invention further concerns compositions and processes for the manufacture of polyurethane articles using the organometallic compounds as catalysts to provide cured articles having a comparable performance to those produced using a commercial mercury-based catalyst.

    Abstract: Dehydroxylated oxide (e.g. silica) particles are obtained by reacting oxide particles, having surface hydroxyl groups, with a dialkylcarbonate or diarylcarbonate. The resulting products have surface alkoxy or aryloxy groups and significantly reduced hydroxyl content. The treated oxide particles are especially suitable for use as catalyst supports, and especially as polyolefin catalyst supports.

    Abstract: A hydrogenation catalyst consisting essentially of (A) at least one bis(cyclopentadienyl)titanium compound represented by the formula (1): ##STR1## wherein R.sup.1 and R.sup.2, which may be the same or different, represent halogen atoms, hydrocarbon groups, aryloxy groups, alkoxy groups or carbonyl groups, and (B) at least one lithium compound represented by the formula (2):R.sup.3 O--Li (2)wherein R.sup.3 represents a hydrocarbon group, or a reaction mixture of an organolithium compound with an alcoholic or phenolic hydroxyl group-containing compound, the (A) component/the (B) component molar ratio being 1/0.5 to 1/20, and optionally (C) at least one reducing organometallic compound selected from the group consisting of aluminum compounds, zinc compounds and magnesium compounds, the (A) component/the (C) component molar ratio being 1/0.5 to 1/20. The above hydrogenation catalyst is effectively applied to the hydrogenation of a polymer having olefinic double bonds to produce a hydrogenated polymer having a high degree of hydrogenation at a high hydrogenation rate with a high reproducibility.
