    • Processes for the alcoholysis, inclusive of transesterification and/or disproportionation, of reactants are disclosed. The alcoholysis process may include feeding reactants and a trace amount of soluble organometallic compound to a reactor comprising a solid alcoholysis catalyst, wherein the soluble organometallic compound and the solid alcoholysis catalyst each independently comprise a Group II to Group VI element, which may be the same element in various embodiments. As an example, diphenyl carbonate may be continuously produced by performing transesterification over a solid catalyst followed by disproportionation, where a trace amount of soluble organometallic compound is fed to the transesterification reactor. Also disclosed is a process for reactivating a spent solid alcoholysis catalyst, such as a catalyst useful for transesterifications and/or disproportionations, the process including removing polymeric materials deposited on the catalyst and re-depositing catalytically active metals on the solid catalyst.

    • A method of increasing the TON of a catalyst system for the monocarbonylation of ethylenically unsaturated compounds using carbon monoxide in the presence of a co-reactant, other than water or a source thereof, having a mobile hydrogen atom is described. The catalyst system is obtainable by combining: (a) a metal of Group (8, 9) or (10) or a suitable compound thereof; (b) a ligand of general formula (I) wherein the groups X3 and X4 independently represent univalent radicals of up to 30 atoms or X3 and X4 together form a bivalent radical of up to 40 atoms and X5 has up to 400 atoms; Q1 represents phosphorus, arsenic or antimony; and c) optionally, a source of anions. The method includes the step of adding water or a source thereof to the catalyst system. The method is preferably carried out in the presence of an electropositive metal.
