The invention relates to a process for the oxidation of carbon-containing organic compounds where the said compounds have at least one bond with a bond order >1, wherein an oxidizing of these carbon-containing organic compounds to be oxidized is performed with electrochemically generated C—O—O oxidizing agents, in particular peroxodicarbonate. Also described is the use of C—O—O oxidizing agents generated electrochemically from carbonate, in particular peroxodicarbonate, as oxidizing agents for the oxidation of carbon-containing organic compounds, in particular carbon-containing organic compounds where the said compounds have at least one bond with a bond order >1. Finally, an arrangement for the oxidation of carbon-containing organic compounds is provided, comprising a first unit for the electrochemical preparation of C—O—O oxidizing agents generated electrochemically from carbonate, in particular peroxodicarbonate, and a second unit for the oxidizing of the carbon-containing organic compound with the C—O—O oxidizing agent generated electrochemically from carbonate, in particular peroxodicarbonate. In this case, these two units are connected to one another in such a way that an ex situ generated oxidizing agent can be fed to the second unit.

An electrochemical method for C&#x2014;C coupling a phenol and an aniline in a reaction vessel containing a suitable solvent or solvent mixture and a conductive salt to produce biaryls having both hydroxyl and amino functions, wherein the difference in the oxidation potentials &#x394;E of the substrates ranges from 10 mV to 450 mV and the substrate with the highest oxidation potential is in excess, which method dispenses with multi-step syntheses using metallic reagents.

Electrochemical process for coupling of phenol to aniline

An electrochemical method for coupling anilines. When coupling two different anilines, the difference of the oxidation potential of the substrates is in the region of between 10 mV to 450 mV, and the aniline with the highest oxidation potential is added in excess. The method allows biaryldiamines to be electrochemically produced, and can avoid the need for multi-step syntheses using metallic reagents.

Electrochemical coupling of anilines

An electrolyte composition (A) containing (i) at least one aprotic organic solvent; (ii) at least one conducting salt; (iii) at least one compound of formula (I) wherein A, A, A, A, A, and Aare independently from each other selected from H and F, wherein at least one of the group A, A, A, A, A, and Ais F; R is selected from R, and C(O)OR, and Ris selected from C-Calkyl, C-Ccycloalkyl, C-Calkenyl, C-Ccycloalkenyl, C-C(hetero)aryl, and C-Calkinyl, wherein alkyl, cycloalkyl, alkenyl, cycloalkenyl, (hetero)aryl, and alkinyl may be substituted by one or more F; and (iv) optionally at least one further additive.

2,2'-diaminobiaryls having two secondary amines

An electrochemical treatment of differently protected aniline or napthylamine results in the preparation of unsymmetrical 2, 2'-diaminebiaryls provided with different protecting groups. The treatment involves the protecting groups prior to the C, C coupling step. The co-reactants generally have different oxidation potentials which results from the selection of the protecting groups. The treatment also enables controlled access to the individual amino functions of the 2, 2&#x2032;-diaminobiaryls by subsequent selective deprotection.
