Disclosed are electroluminescent metal complexes with triazoles of the formula (I), where n1 is an integer of 1 to 3, m1 and m2 each are an integer 0, 1 or 2, Mis a metal with an atomic weight of greater than 40, Lis a monodentate ligand or a bidentate ligand, Lis a monodentate ligand, Qstands for an organic bridging group completing, together with the bonding carbon atoms of the triazole ring, an annellated, carbocyclic or heterocyclic, non-aromatic ring, which optionally may be substituted, Qrepresents a group of forming a condensed aromatic, or heteroaromatic ring, which can optionally be substituted, as well as new intermediates for the preparation of these complexes, electronic devices comprising the metal complexes and their use in electronic devices, especially organic light emitting diodes (OLEDs), as oxygen sensitive indicators, as phosphorescent indicators in bioassays, and as catalysts. 

Electroluminescent metal complexes with triazoles

The present invention relates to a process for the preparation of compounds of formula (1), in which R , R and R independently of one another are hydrogen, halogen , trifluoromethyl of or C -C alkoxy, wherein a compound of formula (2), in which R , R and R are as defined in formula (1), is reacted with methlyamine in the presence of a non-alcoholic solvent and, if desired, in the presence of a sulfonic acid catalyst to give the compound of formula (2) and, if desired, is subject to purification by recrystallization.

Process for the preparation of ketimines

Described is a process for the preparation of compounds of formula (1a) which comprises reacting an isomeric mixture consisting of from 75 to 95% of compound of formula (2a) and from 5 to 25% of a compound of formula (2b) with methylamine, in a suitable solvent, to form a sertraline-imine isomeric mixture consisting of from 75 to 95% of formula (1a) and from 5 to 25% of formula (1b)(A ), or reacting an isomeric mixture consisting of from 75 to 95% of a compound of formula (2a) and from 5 to 25% of a compound of formula (2b) with methylamine, in a suitable solvent, using suitable methods of isolation to form an enriched sertraline-imine isomeric mixture, consisting of >99% of a compound of formula (1a) and <1% of a compound of formula (1b)(A ); and then subjecting the sertraline-imine isomeric mixture obtained according to reaction route (A ) or (A ), in a suitable solvent, to recrystallisation (B), in accordance with scheme (I) wherein in formula (1a), R , R and R are each independently of the others hydrogen, halogen, trifluoromethyl or C -C alkoxy and formulae (1b), (2a) and (2b) are as defined in the description.

The invention relates to compositions of hexacoordinated ruthenium and osmium carbenes with a carbonyl group as ligand and a vinyl group as substituent on the carbene group as catalysts for the photoinduced ring-opening metathesis of strained cycloolefins. It also relates to novel hexacoordinated ruthenium and osmium carbenes having a carbonyl group as ligand and a vinyl group as substituent on the carbene group, to compositions of the catalyst with cycloolefins, and to the polymerization process.

Ruthenium and osmium carbene carbonyl catalysts

Heterocyclyl ligand containing ruthenium and osmium catalysts

A process for the preparation of a metal carbene, in which a metal salt is first reacted in the presence of a base and a secondary or tertiary alcohol with a tertiary phosphine or phosphite or a ditertiary diphosphine or diphosphite and then reacted in the presence of an acid with an alkyne and, if desired, an alkene.
