  • FLUIDIZABLE CARBON CATALYSTS
    Publication number: 20070299277
    Abstract: Disclosed are fluidizable catalysts comprising carbonized, polysulfonated vinylaromatic polymer particles. These carbonized polymer particles can be active catalysts by themselves or can act as supports for active catalyst components. These novel catalysts show excellent fluidization behavior over a wide range of gas velocities. Also disclosed are processes for making fluidizable catalysts, for fluidizing these catalysts, and for the preparation of carbonylation products with these catalysts.

  • Process for generating pivaloylacetate esters via carbonylation of chloropinacolone
    Publication number: 20060149094
    Abstract: Pivaloylacetate esters (1) are a useful intermediates for producing chemicals for use in photographic and xerographic reproduction processes. Such esters can be generated by contacting chloropinacolone (2) with CO, an alcohol of formula R1OH, and a base in the presence of a catalyst comprising a source of palladium and certain coordinating trisubstituted phosphines of formula (R3)3P.

  • Carbonylation of alpha-chloroketones to beta-keto esters using palladium carbene catalysts
    Publication number: 20060149095
    Abstract: The present invention is a novel process for producing ?-ketoesters 1 by contacting an ?-chloroketone 2 with carbon monoxide and a hydroxyl-containing compound of formula R3OH in the presence of a base and a palladium carbene catalyst complex 3. The subject catalysts demonstrate superior rates and selectivity when compared to known (Ph3P)2PdCl2.
