Abstract
Oxidative ligand coupling of organoborates is promoted by chlorosilane and molecular oxygen. When tetraarylborate compounds are treated with Ph2SiCl2 or PhSiCl3 in acetonitrile under an oxygen atmosphere, the corresponding bi aryls are obtained in good yields. Use of unsymmetrical borates results in the selective formation of unsymmetrical biaryls.
