在温和条件下，铜（I）配合物[Cu 1（TMPA）CH 3CN] PF 6（TMPA =三（2-吡啶甲基）胺）与苄基和烯丙基卤化物以及α-卤代酮按化学计量反应，分别产生接近定量产率的碳-碳还原偶联产物联苄基、二烯烃或二酮。 铜配合物作为卤化物受体，并且还分离出铜（II）配合物[Cu（II）（TMPA）X] PF 6（X = Cl-或Br-）。 没有确切的机制结论可以得出，但氧化添加的RX产品，即有机铜（II）或铜（III）的中间体，建议。
Under mild conditions, the copper(I) complex [Cu1(TMPA)CH3CN]PF6 (TMPA = tris(2-pyridylmethyl)amine), reacts stoichiometrically with benzyl and allyl halides, and alpha-halo-ketones to produce near quantitative yields of carbon-carbon reductively coupled products bibenzyls, diolefins or diketones, respectively. The copper complex acts as the halide acceptor and the copper(II) complex [Cu(II)(TMPA)X]PF6 (X = Cl- or Br-) is also isolated. No firm mechanistic conclusions can be drawn, but the intermediacy of oxidatively added RX products, i.e. organo-Cu(II) or Cu(III), is suggested.
