    Abstract: The invention relates to a method for preparation of ruthenium-based carbene catalysts with chelating alkylidene ligands (so-called “Hoveyda-type catalysts”) in a cross metathesis reaction by reacting a ruthenium-alkylidene complex with an olefin derivate in the presence of a polymer-supported cation-exchange resin (PSR) acting as a ligand (i.e. phosphine or amine) scavenger. Preferably, penta-coordinated ruthenium benzylidene or indenylidene carbene complexes are employed. The polymer-supported cation-exchange resin (PSR) may be an acidic resin (comprising sulfonic acid or carboxylic groups) or a resin containing carboxylic acid chloride (—COCl) groups or sulfonyl chloride (—SO2Cl) groups. The process is versatile and environmentally friendly; high yields are obtained.

    Abstract: Methods of forming single source precursors (SSPs) include forming intermediate products having the empirical formula ½{L2N(?-X)2M?X2}2, and reacting MER with the intermediate products to form SSPs of the formula L2N(?-ER)2M?(ER)2, wherein L is a Lewis base, M is a Group IA atom, N is a Group IB atom, M? is a Group IIIB atom, each E is a Group VIB atom, each X is a Group VIIA atom or a nitrate group, and each R group is an alkyl, aryl, vinyl, (per)fluoro alkyl, (per)fluoro aryl, silane, or carbamato group. Methods of forming polymeric or copolymeric SSPs include reacting at least one of HE1R1E1H and MER with one or more substances having the empirical formula L2N(?-ER)2M?(ER)2 or L2N(?-X)2M?(X)2 to form a polymeric or copolymeric SSP. New SSPs and intermediate products are formed by such methods.

  • Publication number: 20120142954
    Abstract: The present invention is directed to a method of exchanging nanostructures from within aqueous liquid media into organic liquid media. The steps comprise first supplying solid nanostructures in an aqueous liquid media, adjusting the pH, incorporating an ionic surfactant sufficient to reduce nanostructure aggregation, followed by concentrating the nanostructures in the aqueous liquid media. The nanostructures may them be placed in organic liquid media followed by introduction of a coupling agent capable of covalent attachment to the nanostructure surface while providing a functional group capable of polymerization to covalently bond the nanostructures to a selected monomer and/or polymer resin.
