Method for catalytic and selective oxidation of aromatic compounds

Process for selective catalytic oxidation of olefins to aldehydes, ketones with cleavage of C&equals;C bonds

The present invention relates to a process for the preparation of organorhenium oxides from rhenium-containing compounds, where the rhenium-containing compound is reacted with a silylating agent and organylating reagent, and the rhenium-containing compound originates in particular from the residue from a spent organorhenium oxide catalyst or rhenium oxide catalyst.

Direct synthesis of organorhenium oxides from compounds containing rhenium

The invention relates to a process for the preparation of an amine by single-stage reaction of a C.sub.2 -C.sub.20 -olefin with a compound having an NH.sub.3 group, hydrogen and carbon monoxide, wherein the reaction takes place in the presence of a catalyst, which is present in water in dissolved or suspended form, and the catalyst contains at least two metals from group VIII of the Periodic Table of the Elements in elemental or bonded form.
