report an aryne triggered ring-opening fluorination protocol of a great variety of saturated sulfur heterocycles. A key factor for the success is the identification of a suitable mediator. Compared to previous methods, this transition-metal free protocol employs low-cost potassium fluoride as the fluorine source. The operational simplicity and mild reaction conditions allow for the rapid synthesis of a
Organosulfides are a common class of structure units in bioactive molecules and functional materials motivating continuous developments of efficient synthetic methods. Herein, we report an electrophilic aryne-activated ringopening protocol of one or two heteroatom containing saturated sulfur heterocycles. This three-component transformation proceeds under mild reaction conditions and displays exceptional

boronic acid as an efficient surrogate of hydroxide upon activation via fluoride complexation. The hitherto unknown aryne induced ring-opening reaction of cyclic sulfides and three-component coupling of fluoro-azaarenes are developed to exemplify the application value. Different from metal hydroxides or water, this novel hydroxy source displays mild activation conditions, great functionality tolerance
硼酸已成为现代有机合成中最普遍的试剂类别之一,通过C-B 键断裂显示出各种反应特性。在此,我们描述了利用一种现成的硼酸作为氢氧化物的有效替代物,通过激活氟化物络合。开发了迄今为止未知的芳炔诱导的环硫化物开环反应和氟氮杂芳烃的三组分偶联反应,以举例说明其应用价值。与金属氢氧化物或水不同,这种新型羟基源显示出温和的活化条件、良好的功能耐受性和结构可调性,这将产生一种新的合成范式,并在广泛的背景下为有机硼化学提供新的蓝图。详细的计算研究还识别了氟化物激活模式,提供了对前所未有的机制途径的深入见解,并阐明了 ArB(OH) x F y配合物的反应性差异,这充分支持了实验数据。
