摘要:
The present invention relates to a method for the hydroxylation of halogen aryl compounds carried out at a temperature lower than 200°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.
摘要:
The present invention relates to a process for creating a Carbon-Carbon bond (C—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—C or C-HE bond, wherein the reaction takes place in the presence of an effective quantity of a catalytic system comprising iron and copper.
