Abstract: This invention relates to the preparation of allyl vinylacetate esters via the catalytic carbonylation of allylic alcohols. The esters are produced in good yield and selectivity using empirically selected 3-component homogeneous palladium dihalide catalysts consisting essentially of 1) palladium(II) halides stabilized with 2) one or more Group VB donor ligands, and 3) in combination with Group IVB metal halide cocatalysts such as tin(II) halides, tin(IV) halides and germanium(II) halides. An improvement in shorter reaction times, increased yields and selectivity over what has been reported in the literature has been found to be attributable to the use of applicant's catalysts rather than the catalysts used in the art.

Abstract: This invention relates to the catalytic carbonylation of .alpha.,.alpha.'-dihaloxylenes to phenylenediacetate diesters by the catalytic insertion of carbon monoxide into the carbon-halogen bonds of said .alpha.,.alpha.'-dihaloxylenes in the presence of alkanols. The catalysts used in this novel process are two component homogeneous ligand-stabilized palladium(II) and nickel(II) halide complexes wherein said stabilizing ligands each contain at least one Group VB or VIB donor atom such as phosphorus, which is bonded to one or more aromatic and/or aliphatic radicals.

Abstract: This invention concerns using mineral acid treatment for the regeneration of carbonylation and hydroformylation catalysts consisting of dispersions of ligand-stabilized palladium(II) and platinum(II) halide complexes in quaternary ammonium, phosphonium and arsonium salts of trihalostannate(II) and trihalogermanate(II).

Abstract: This invention concerns chlorinating processes for the regeneration of carbonylation and hydroformylation catalysts consisting of dispersions of ligand-stabilized palladium(II) and platinum(II) halide complexes in quaternary ammonium, phosphonium and arsonium salts of trihalostannate(II) and trihalogermanate(II).

Abstract: This invention relates to a process for preferentially and selectively hydroformylating .alpha.-olefins present in a mixture of .alpha.-olefins and internal olefins, said hydroformylation being catalyzed by a class of ligand-stabilized platinum (II) dihalide complexes in combination with Group IVB metal halides.

Abstract: This invention relates to the carbonylation of unsaturated aliphatic halides by the insertion of carbon monoxide into the carbon-halogen bond of said unsaturated aliphatic halide, in the presence of a hydroxylated coreactant, to form an unsaturated, halogen-free, aliphatic ester, using as catalyst homogeneous noble metal complexes with Group VB donor ligands in combination with Group IVB metal halides.

Abstract: This invention concerns the reduction of nitroparaffin substrates to the corresponding oxime in a carbon monoxide atmosphere under moderate reaction conditions using silver salt catalysts solubilized in nitrogenous base.

Abstract: This invention relates to the hydroformylation of alkyl olefins to form aldehydes by the addition of hydrogen and carbon monoxide using ligand stabilized platinum(II) dihalide complexes in combination with Group IVB metal halides as catalysts.

Abstract: This invention concerns a process for preparing linear fatty (carboxylic) acids and esters from the reaction of olefins, alcohols (or water) and carbon monoxide. The process is catalyzed by catalytic amounts of dispersions of ligand-stabilized, palladium(II) halide complexes, in quaternary ammonium, phosphonium or arsonium salts of trihalostannate(II) or trihalogermanate(II). These empirically selected palladium catalysts can be recycled with fresh olefin feed several times before substantial loss of catalytic activity is encountered.

Abstract: This invention concerns the preparation of linear saturated and unsaturated aliphatic thiol esters by the catalytic addition of carbon monoxide plus a sulfur containing nucleophile having a mobile hydrogen atom, to the carbon-to-carbon unsaturated bond of a 1-alkene or 1-alkyne, using homogeneous noble metal, bimetallic catalyst complexes.

Abstract: This invention concerns an improved process for preparing monocarboxylated derivatives of cyclododecatriene by the catalytic addition of carbon monoxide using certain homogeneous, experimentally selected, three component, ligand-stabilized, platinum(II) or palladium(II)-Group IVB metal halide catalyst compositions.Optionally, in the case of certain ligand-stabilized, platinum(II) halide-Group IVB metal halide catalyst complexes, the above carboxylated reaction mixture containing alkyl cyclododecadiene carboxylate can be purged of carbon monoxide, hydrogen can be passed into the reaction mixture, the reaction mixture pressurized in a hydrogen atmosphere and the carbon-to-carbon double bonds in said alkyl cyclododecadiene carboxylate intermediate reduced.
