symmetrical ethers and/or N-substituted carboxylic amides. While with most phosphane ligands tested, the dominating product is always the ether, with the trimesitylene ligand the amides are the major products. The reaction conditions are much milder than those reported previously. Mechanistic control experiments with a chiral alcohol prove the intermediacy of carbenium ions, further studies with not readily
在金催化的转化作用下,苯甲腈和腈可提供对称的醚和/或N-取代的羧酸酰胺。尽管对大多数膦配体进行了测试,但主要的产物始终是醚,而对于1,3,5-苯三甲基配体而言,酰胺是主要产物。反应条件比以前报道的温和得多。用手性醇进行的机械控制实验证明了碳正离子的中间性,对不易电离的醇的进一步研究表明,对于苯氢化合物,碳正离子和金(I)-羟基络合物是中间体。
