  Hiyama coupling reaction of fluorous alkenyl-fluorosilanes: Scope and mechanistic considerations

  摘要：

  Novel fluorous alkenyl-fluorosilanes (CnF2n+1CH=CHSiMe2F; n = 4, 6, 8; 5a-c) were synthetized in a three step procedure from perfluoroalkyliodides and dimethylvinylchlorosilane. They were first reacted with iodobenzene at room temperature in Hiyama coupling reaction (DMF, Pd(OAc)(2), TBAF, 72 h) to afford the appropriate omega-perfluoroalkyl-styrenes (CnF2n+1CH=CHC6H5, n = 4, 6, 8): then the reactivity of 5a with monosubstituted iodobenzenes was studied. The coupling reaction of Sa with o-substituted iodobenzenes usually failed, while that of with the m- and p-substituted ones gave fluorous styrenes [m- or p-(C4F9CH=CH)C6H4X], independently of the electronic effect of their substituent (X = Br, CF3, CH3, OCH3). These volatile products can easily be isolated by steam-distilltaion and purified further by distillation. The mechanism of the above coupling reactions was a pure Hiyama type involving fluoride-ion induced transmetallation without any Heck type contribution, since no coupling product of C6F13CH=CH2 and C6H5I was observed in blank control experiments using similar conditions (DMF, TBAF, Pd(OAc)(2), 72 h, 25 degrees C).
