The present invention concerns a process for creating a Carbon-Carbon bond (C&#x2014;C) or a Carbon-Heteroatom bond (C&#x2014;HE) by reacting a compound carrying a leaving group with a nucleophilic compound carrying a carbon atom or a heteroatom (HE) that can substitute for the leaving group, creating a C&#x2014;C or C&#x2014;HE bond, wherein the reaction takes place in the presence of an effective quantity of a. a catalytic system comprising a ligand and at least a metal-based catalyst, such a metal catalyst being chosen among iron or copper compounds proviso that only a single metal is present.

Catalytic system for cross-coupling reactions

The present invention concerns a process for creating a Carbon-Carbon bond (C&#x2014;C) or a Carbon-Heteroatom bond (C-HE) by reacting a compound carrying a leaving group with a nucleophilic compound carrying a carbon atom or a heteroatom (HE) that can substitute for the leaving group, creating a C&#x2014;C or C-HE bond, wherein the reaction takes place in the presence of an effective quantity of a. a catalytic system comprising a ligand and at least a metal-based catalyst, such a metal catalyst being chosen among iron or copper compounds proviso that only a single metal is present.

Iron-copper co-catalyzed process for carbon-carbon or carbon-heteroatom bonding

The present invention relates to a method for the hydroxylation of halogen aryl compounds carried out at a temperature lower than 200&#xb0; C. in the presence of a catalytic system including a copper-based catalyst and a ligand L according to reaction scheme Formula (A), in which: R is selected from the groups having an acceptor inductive effect and the groups having a donor mesomer effect; M is selected from alkaline or alkaline-earth cations; X is a halogen atom; r is between 0 and 5; and the ligand L is selected from compounds having formula I. 

Method for the hydroxylation of halogenated aryl compounds

The invention relates to a method for preparing arylamines and, in particular, a method for preparing aniline and anilines substituted on the aromatic ring from ammonia, under easily-industrialized mild conditions with good selectivity and yields, in the presence of a catalytic system including a copper complex.
