remarkable fluorine effect on “on water” reactions is reported. The CF⋅⋅⋅HO interactions between suitably fluorinated nucleophiles and the hydrogen‐bond network at the phase boundary of oil droplets enable the formation of a unique microstructure to facilitate on water catalyst‐free reactions, which are difficult to realize using nonfluorinated substrates. Accordingly, a highly efficient on water, catalyst‐free
据报道,氟对“水”反应有显着的影响。与c F⋅⋅⋅H ö适当氟化亲核和在油滴的相界的氢键网络使一个唯一的微结构的形成,以促进对水无催化剂的反应,这是难以用给实现之间的相互作用非氟化底物。因此,开发了一种高效的水,二氟乙烯硅烷与醛,活性酮和异亚丙基丙二腈的无催化剂反应,从而导致各种α,α-二氟-β-羟基酮和季吲哚的高效合成。 。
