method to generate 1,2-cyclohexadienes by fluoride-induced β-elimination of 6-(trimethylsilyl)cyclohexenyl triflates is presented. This method allows the generation of these highly strained cyclic allenes in good yields and under mild reaction conditions, as demonstrated by trapping experiments based on cycloaddition reactions.

提出了一种通过氟化物诱导 β-消除 6-(三甲基甲硅烷基) 环己烯基三氟甲磺酸酯生成 1,2-环己二烯的改进方法。这种方法可以在温和的反应条件下以良好的收率和温和的反应条件生成这些高度应变的环状丙二烯,正如基于环加成反应的捕获实验所证明的那样。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
