Carbon–carbon cross-coupling reactions are very important in the areas of material science and medicinal chemistry.[1] Transition-metal-catalyzed cross-coupling of organometallic reagents (nucleophiles) with halides or triflates (electrophiles) constitutes one of the most powerful methods for constructing CÀC bonds.[2] Arene-and alkanesulfonyl chlorides are inexpensive and readily available compounds. We have shown that Stille, carbonylative ...
