pyrrole in the presence of silver(I) triflate proceeds smoothly at room temperature to give a pyrromethane in excellent yield. The azafulvenium ion, an active form that reacts with α-free pyrrole, also reacts with pyrromethane rapidly under similar neutral conditions to afford an equilibrated mixture of pyrromethanes in good yield.
在三氟甲磺酸银(I)存在下,2-巯基苯并噻唑基甲基吡咯与无α-吡咯的偶联反应在室温下顺利进行,从而以优异的产率得到吡咯甲烷。氮杂富烯鎓离子是一种与无α吡咯反应的活性形式,在相似的中性条件下也能与吡咯甲烷快速反应,从而以高收率提供了一种平衡的吡咯甲烷混合物。
