The conversion of aryl alkenes into β‐nitrostyrenes or benzonitriles with NaNO2 can be governed by an appropriate choice of ionic liquid medium. A general trend was found for the selectivity of these processes, which depends on the nature of IL, with imidazolium‐based ILs, such as [Bmim] Cl, that favor the formation of β‐nitrostyrenes, while tetraalkylammonium‐based ILs, such as TBAA, that favor the
芳基烯烃成β-硝基苯乙烯或苄腈具有纳米的转化2可以通过离子的液体介质的适当选择来控制。对于这些过程的选择性,发现了一个总体趋势,这取决于离子液体的性质,咪唑类的离子液体,例如[Bmim] Cl,有利于β-硝基苯乙烯的形成,而四烷基铵基的离子液体,例如TBAA,有利于苄腈的形成。
