Definitions
- the following invention relates to an electrochemical process for the coupling of phenol and aniline.
- anilines and phenols are used in this application as a generic term and thus also includes substituted aminoaryls and substituted hydroxyaryls.
- a major disadvantage of the above-mentioned methods of phenol-aniline cross-coupling is the frequent need for dry solvents and exclusion of air. Furthermore, often large amounts of partially toxic oxidizing agents are used. During the reaction often occur toxic by-products, which are consuming separated from the desired product and expensive must be disposed of. Dwindling raw materials (eg, boron and bromine in the case of transition-metal-catalyzed cross-coupling) and the increasing relevance of environmental protection are raising the price of such transformations. Especially when using multi-level sequences, a change of different solvents is necessary.
- a problem that arises in the electrochemical coupling of different molecules is that the reactants usually have different oxidation potentials E 0x .
- the molecule with the lower oxidation potential has a higher tendency to donate an electron (e " ) to the anode and an H + ion to, for example, the solvent than the molecule with the higher oxidation potential E 0x via the Nernst equation:
- the object of the following invention was to provide an electrochemical process in which anilines and phenols can be coupled together, and can be dispensed with multi-stage syntheses using metallic reagents.
