A process for the preparation of vinyl, alkynyl, aryl or heteroaryl aldehydes or vinyl, alkynyl, aryl or heteraoryl ketones includes reacting vinyl-, alkynyl-, aryl- and heteroarylmethyl and -methylene compounds with the aid of a mediator and an oxidant, wherein the mediator is selected from the group of the aliphatic, heterocyclic or aromatic NO, or NOH containing compounds.

Process for the preparation of aldehydes and ketones

Multi-component system for modifying, degrading or bleaching lignin, lignin-containing materials or similar substances, includes (a) if appropriate at least one oxidation catalyst; (b) at least one suitable oxidizing agent; and (c) at least one mediator, wherein the mediator is chosen from the group consisting of N-aryl-N-hydroxyamides.

Multi-component system for modifying, degrading or bleaching lignin, lignin-containing materials or similar substances

A multicomponent system for modifying, degrading or bleaching lignin and lignin-containing materials or similar substances, includes an oxidoreductase and an oxidant suitable for the oxidoreductase and a mediator and at least one enzymatically active additive. The mediator does not inactivate the oxidoreductase and the enzymatically active additive, and the enzymatically active additive is selected from the group consisting of the hydrolases of the enzyme class 3.2.1.

Multicomponent system for modifying, degrading or bleaching lignin or lignin-containing materials, and processes for its use

According to the inventive method for producing organic hydroxylamines, at least one organic nitro compound is partially hydrogenated in the presence of an organic base or ammonia, a trivalent phosphor compound and a hydrogenation catalyst. The invention is characterised in that quantities of the nitrogen base of more than 10 wt. % in relation to the organic nitro compound are used.

Method for producing organic hydroxylamines

Process for the preparation of heteroaryl aldehydes or heteroaryl ketones by reaction with heteroarylmethanols with the aid of a mediator and an oxidant, wherein the mediator is selected from the group of the aliphatic, cycloaliphatic, heterocyclic or aromatic NO, and NOH containing compounds.

Process for the preparation of heteroaryl aldehydes and heteroaryl ketones

A process for the preparation of vinyl, alkynyl or aryl aldehydes or vinyl, alkynyl or aryl ketones by reaction of vinyl-, alkynyl- or aryl- methanols with the aid of a mediator and an oxidant, wherein the mediator is selected from the group of the aliphatic, cycloaliphatic, heterocyclic or aromatic NO or NOH containing compounds.
