测量了取代芳烃磺酸的酯、阴离子和酰胺以及取代芳烃磺酸的酯和酰胺中末端氧原子的 17O NMR 谱。末端 O 的信号看起来接近桥 O 的信号。 与羰基 O 相比,末端 SO 显示 (a) 对孪晶基团的电子影响的敏感性较低,(b) 对芳烃环取代基的敏感性较低(c) 小的溶剂效应。根据 π 键特性讨论 C 键和 S 键 O 之间的差异。Dy3+ 与甲基芳烃亚磺酸盐中的 O 端发生络合。
isoquinolin-1(2H)-ones at the C-4 position is reported by employing ethyl sulfinates, and the corresponding products are obtained in moderate to excellent yields in the presence of iodine. This synthetic strategy provides a range of thioether-isoquinolin-1(2H)-ones while tolerating a number of functional groups on the isoquinoline nitrogen atom and benzene ring. In addition, pyridin-2(1H)-one is also reacted
