Cyclopalladated ferrocenylimines catalyzed-homocoupling reaction of arylboronic acids in aqueous solvents at room temperature under ambient atmosphere

In the presence of 0.1–0.5 mol% cyclopalladated ferrocenylimine with dodecyl chain, various arylboronic acids underwent homocoupling reaction in n-PrOH/H2O (v/v = 1:2) under aerobic atmosphere without elevated heating to give rise to symmetrical biaryls in moderate to good yields.
