Abstract: Methods for the cross-metathesis of polysaccharides with one or more olefin-terminated side chains and cross-metathesized products are described. In an exemplary embodiment, a method for the synthesis of cellulose ?-carboxyesters via olefin cross-metathesis with acrylates is described. Conditions of the reactions were relatively mild and the olefin-substituted polysaccharides and the appropriate acrylate partners appear to follow Grubbs rules as summarized herein. Additionally, a method of hydrogenation of the cross-metathesized product is described. The compounds and methods may be useful for waterborne coating applications, adhesives, lubricants, or any product in need of dispersion in an aqueous media.

Abstract: A method for the electrochemical production silicon comprises applying an electrical potential across an anode and a cathode to provide electrons at the cathode. The anode and the cathode are in contact with an electrolyte melt at a reaction temperature. The electrolyte melt comprises a molten salt or a mixture of molten salts; a silicon-containing precursor at least partially dissolved in the electrolyte melt to provide soluble silicon-containing ions in the electrolyte melt; and a supporting electrolyte at least partially dissolved in the electrolyte melt to provide O2? ions in the electrolyte melt. The soluble silicon-containing ions at the cathode undergo reduction reactions with the electrons to release O2? ions and deposit silicon on the cathode.
