The reaction of N-arylimines of hexafluoroacetone and CF3Si(CH3)3 (1) in the presence of CsF results in a 48–84% yield formation of ArN(H)C(CF3)3. The reaction requires an equimolar amount of CsF and rapidly proceeds in solvents such as THF or monoglyme. Interaction of CF3NC(CF3)2 with excess of 1 leads to the formation of novel amine [(CF3)3C]2NH. Stable salt of this amine is isolated in a reaction
在CsF存在下,六氟丙酮的N-芳基丙氨酸与CF 3 Si(CH 3)3(1)的反应导致ArN(H)C(CF 3)3的产率为48-84%。该反应需要等摩尔量的CsF,并在溶剂(如THF或一糖单体)中快速进行。CF的相互作用3 NC(CF 3)2与过量的1所导致新的胺[(CF的形成3)3 C] 2 NH。在异构体CF 3 CF 2 N = CFCF的反应中分离出这种胺的稳定盐在CsF存在的情况下,3超过1。
