Carbostannylation of alkynes with tributyl(3,3,3-trifluoropropynyl)stannane is found to proceed at room temperature in a syn-manner, giving rise to the corresponding CF3-substituted enynes as a single stereoisomer in good yields. Both terminal and, CF3- or RO2C-substituted internal alkynes are applicable to the addition reaction. Synthetic applications of the adduct are also demonstrated.
用三丁基(3,3,3-三氟丙炔基)锡进行炭锡化反应发现该反应在室温下以同位旋的方式进行,生成相应的CF3取代的烯炔,且以单一立体异构体的形式获得良好产率。终烯和CF3或RO2C取代的内烯均适用于该加成反应。还展示了该加成物的合成应用。
