metal‐free protocol for the domino trifluoromethylthiolation/decarboxylation of β‐ketocarboxylic acids is described. The catalytic reactions take place in acetonitrile in the presence of aqueous ammonium hydroxide and N‐trifluoromethylthiosaccharin. The sequence of events and reaction mechanism were established experimentally and using density functional theory calculations. This synthetic method offers a convenient
描述了用于β-酮羧酸的多米诺三氟甲基硫醇化/脱羧的无金属方案。催化反应在含水氢氧化铵和N-三氟甲基硫代糖精存在下于乙腈中进行。实验的顺序和反应机理是通过实验确定的,并使用了密度泛函理论计算。这种合成方法为合成α-三氟甲硫基取代的酮的已知途径提供了一种方便的替代方法。
