Process for the biocatalytic coupling of aromatic compounds in the presence of a radical transfer agent

摘要: A process is described for the dimerization of a substituted aromatic compound formula (I) wherein X represents -OH, -SH or -NHR where R H, an alkyl group aryl group; R?1 and R2? represent group, alkenyl alkynyl alicyclic halogen atom, alkoxy aryloxy hydroxy amino R?3 R4? can have same definition as may additionally hydrogen atom; which comprises reacting in presence peroxidase enzyme, peroxide radical transfer agent aqueous medium.
