Abstract
In the presence of NiCl2(PPh(3))(2) as catalyst, p-methoxycarbonylphen y mesylate (5) and tosylate (6) react with lithium arylborates 4 (Ar = 2-furyl; Ph, p-Me-Ph, p-MeO-Ph) at room temperature to afford the cou pling products in high yields. Similarly. mesylates 9-11 coupled with these berates 4 efficiently. Copyright (C) 1996 Elsevier Science Ltd
