Abstract: By screening different organic solvents, it was found that NiCl2•6H2O can catalyze the homocoupling of arylboronic acids using K2CO3 as the base in pyridine to produce symmetrical biaryls in good yield. This reaction can be carried out with exposure to air.

Key words: nickel chloride, arylboronic acid, homocoupling, pyridine
