mesylates and triflates with substituents on the 1-position. These substrates all solvolyze in CD3CO2D to give products derived from cyclopropylcarbinylcations that undergo further rearrangement to give 3-trimethylsilylcyclobutyl cations. These 3-trimethylsilylcyclobutyl cations are stabilized by a long-range rear lobe interaction with the γ-trimethylsilyl group. When the substituent is electron-withdrawing
已经制备了顺-1-羟甲基-2-三甲基甲硅烷基环丙烷的甲磺酸酯衍生物,以及许多相关的甲磺酸酯和在1-位带有取代基的三氟甲磺酸酯。这些底物全部在CD 3 CO 2 D中溶剂溶解,得到衍生自环丙基羰基阳离子的产物,该产物经过进一步重排得到3-三甲基甲硅烷基环丁基阳离子。这些3-三甲基甲硅烷基环丁基阳离子通过与γ-三甲基甲硅烷基的长距离后叶相互作用而稳定化。当取代基是吸电子的(CF 3,CN或CO 2 CH 3),形成大量的双环丁烷产物。双环丁烷是从阳离子中间体中消除了γ-三甲基甲硅烷基的结果,该中间体具有异常长的Si-C键。反式-1-羟甲基-2-三甲基甲硅烷基环丙烷的甲磺酸酯和三氟甲磺酸酯衍生物和1-取代的类似物的溶剂化化学性质可能完全不同,因为这些底物通常不会导致3-三甲基甲硅烷基环丁基阳离子。

An alternative strategy for the mechanochemical defluorinative acylation of ortho-hydroxyarylenaminones has been developed to synthesise 3-acylchromones utilizing CF3-compounds via activation of the C−F bound of the trifluoromethyl group in the presence of ytterbia (Yb2O3). The current protocol tolerated a wide range of coupling substrates to access a library of diversely substituted 3-acylchromones
已经开发出一种用于邻羟基亚芳基氨基酮的机械化学脱氟酰化的替代策略,通过在氧化镱(Yb 2 O 3)存在下激活三氟甲基的CF键,利用CF 3化合物合成3-酰基色酮。当前的方案可耐受多种偶联底物,以在机械化学诱导的多米诺骨牌环化模式下访问不同取代的 3-酰基色酮库。这是第一份关于惰性CF 3基团在机械化学条件下脱氟转化为相应羰基官能团的报告。
