A general and atom-economical method for the synthesis of cyclic sulfoximines by intramolecular imidations of azido-containing sulfoxides using a commercially available FeII phthalocyanine (FeIIPc) as catalyst has been developed. The method conveys a broad functional group tolerance and the resulting three-dimensional heterocycles can be modified by cross-coupling reactions.

Paragraph 0116; 0117; 0119, (2013/10/22)
The present invention relates to the field of catalytic hydrogenation and, more particularly, to the use of specific ruthenium catalysts, or pre-catalysts, in hydrogenation processes for the reduction of ketones and/or aldehydes into the corresponding alcohol respectively. Said catalysts are ruthenium complexes comprising a tetradentate ligand (L4) coordinating the ruthenium with: two nitrogen atoms, each in the form of a primary or secondary amine (i.e. a NH2 or NH group) or N-alkyl imine functional groups (i.e. a C═N group), and two sulfur atoms, each in the form of thioether functional groups.
