In the presence of NiCl2(PPh3)2 as catalyst, p-methoxycarbonylphenyl mesylate (5) and tosylate (6) react with lithium arylborates 4 (Ar = 2-furyl, Ph, p-Me-Ph; p-Me-Ph) at room temperature to afford the coupling products in high yields. Similarly, mesylates 9–11 coupled with these borates 4 efficiently.

Coupling reaction of aryl borates and mesylates derived from phenols and enols was studied. Mesylates with an electron-withdrawing group or ring were highly reactive at room temperature in the presence of NiCl2(PPh3)(2) to furnish the coupling products in good yields.
