    摘要： The invention relates to a method for the catalytic oxidation of benzene to phenol, where the oxidant is hydrogen peroxide and the reaction medium is a mixture of acetonitrile and water, the catalytic oxidation of the benzene being generated by a catalytic system based on copper compounds of formula Tp x Cu(NCCH 3 ). Said method enables approximately 39% conversions of the starting hydrocarbons with phenol selectivities higher than 92% in processes taking place at 60°C with reaction times of between 2 and 4 hours.

    摘要： Novel catalyst compositions comprising a cationic transition metal complex of the formula (Pd(II)S4-xLx)+2(A)-ny, wherein: Pd(II) is palladium having a valence of +2; S is a synthesis solvent; L is a monodendate, bidendate or tridendate ligand or ligands having one or more bonding sites; x is an integer from 1 to 3 and is equal to the total number of ligand bonding sites; A is a weakly or non-coordinating anion capable of stabilizing the complex in its cationic form; and n is 1 or 2 and y is 2 or 1; provided that (i) when n is 1, y is 2 and when n is 2, y is 1; and (ii) when the anion A is tetrafluoroborate, the organometallic complex is not (tris(acetonitrile)palladium(II)triphenylphosphine), (bis(acetonitrile)palladium(II)bis(triphenylphosphine)), ((acetonitrile)palladium(II)tris(triphenylphosphine)) or (bis(acetonitrile)palladium(II) 1,3-bis(diphenylphosphino)propane). The new catalyst compositions are useful for the copolymerization of carbon monoxide and at least one ethylenically unsaturated hydrocarbon to produce linear alternating polymers. The rate of polymerization is enhanced by including an alcohol, such as methanol, in the polymerization mixture.
