    摘要: Acrolein acetals are selectively hydroformylated on the unsaturated carbon atom adjacent to the carbon bearing two ether groups in the presence of a supported rhodium-cobalt bimetallic cluster. The resulting internally hydroformylated product is useful as a precursor of methacrylic acid.

    摘要: Dicyclopentadiene is selectively and substantially hydroformylated to its dimethanolic derivatives by a process comprising contacting dicyclopentadiene with a gaseous mixture of carbon monoxide and hydrogen at a temperature of at least about 100.degree. C. and a pressure of at least about 1,000 psig in the presence of a catalytic amount of a catalyst consisting essentially of a rhodium-cobalt bimetallic cluster, such as Rh.sub.2 Co.sub.2 CO.sub.12, supported on an amine resin, such as DOWEX.RTM. MWA-1.

    摘要: Picolylamines are prepared by reacting (a) cyanopyridine with (b) hydrogen in the presence of a catalytic amount of (c) a palladium on .gamma.-alumina catalyst. The reaction is normally conducted under autogenous or superatmospheric pressure at a temperature of from 20.degree. C. to about 75.degree. C. in a lower alkanol (e.g., isopropanol) as the reaction medium.
