A process for preparing a 2,2′-selenobiaryl ether or a 4,4′-selenobiaryl ether, proceeds by a) adding a first phenol to the reaction mixture, b) adding a second phenol to the reaction mixture, c) adding selenium dioxide to the reaction mixture, d) adding a base having a pKb in the range from 8 to 11 to the reaction mixture, and e) adjusting the reaction temperature of the reaction mixture such that the first phenol and the second phenol are converted to said 2,2′-selenobiaryl ether or said 4,4′-selenobiaryl ether.
