Abstract
The present invention relates to a method for coupling two arenes with selenium dioxide to give a selenobiaryl ether. The method of the present invention includes: adding a first arene to the reaction mixture, adding a second arene to the reaction mixture, adding selenium dioxide to the reaction mixture, adding an acid having a pKa in the range from 0 to 5 to the reaction mixture, and adjusting the reaction temperature of the reaction mixture such that the first arene and the second arene are converted to a selenobiaryl ether. The present invention also relates to novel selenobiaryl ethers.
