Substitution of benzylic H by the title compound (BTF) gives rise to products with −CH(CF3)2 terminus exclusively; an intermediate benzylic ion pair results from hydride transfer. Instead of ion recombination, proton transfer may be the concluding step generating dehydrogenation products and 2,2-bis(trifluoromethyl)ethane-1,1-dicarbonitrile.
标题化合物(BTF)取代苄基H生成仅具有-CH(CF 3)2末端的产物;氢化物转移产生中间的苄基离子对。代替离子重组,质子转移可以是产生脱氢产物和2,2-双(三氟甲基)乙烷-1,1-二腈的最后步骤。
