Converting cyclic amines to lactams using gold supported catalysts.

Process for the conversion of cyclic amines into lactams

The present invention provides a process for the synthesis of an .alpha.,.beta.-unsaturated ester from a mono-olefin-ester using Fe(CO).sub.5.

Process for the synthesis of .alpha., .beta.-unsaturated esters

The present invention provides new catalyst formats which comprise a supported catalyst tethered to a second and different catalyst by a suitable tethering ligand. A preferred system comprises a heterogeneous supported metal catalyst tethered to a homogeneous catalyst. This combination of homogeneous and heterogeneous catalysts has a sufficient lifetime and unusually high catalytic activity in arene hydrogenations, and potentially many other reactions as well, including, but not limited to hydroformylation, hydrosilation, olefin oxidation, isomerization, hydrocyanation, olefin metathesis, olefin polymerization, carbonylation, enantioselective catalysis and photoduplication. These catalysts are easily separated from the products, and can be reused repeatedly, making these systems very economical.

Catalyst system comprising a first catalyst system tethered to a

A method for the removal of sulfur from sulfur-bearing materials such as coal and petroleum products using organophosphine and organophosphite compounds is provided.
