When DBU is added, the cross-coupling reaction between alkyl halides (halogen = Cl, Br and I) and N-haloimides (halogen = Cl, Br) occurs, resulting in the formation of aminated products.

For the first time a systematic research on the catalytic activity of CuXn(X=Cl, Br, I; x=1,2) for the cross-coupling reaction of alkyl halides with Grignard reagents was carried out and environmentally friendly, economical CuBr2showed highest catalytic activity among the catalyst. The conditions of the cross-coupling reaction were studied. The suitable amount of catalyst, reaction temperature and time are 0.3% mol (based on alkyl halide), 67°C (reflux), 6 h, respectively. Under the optimal conditions, the yields of the cross-coupling could reach up to 93%. Moreover, Grignard reagent with an electron-rich group reacted rapidly and with an electron-withdrawing group reacted sluggishly.

To explore plausible reaction pathways of the cross-coupling reaction between a haloalkane and an aryl metal reagent catalyzed by an iron–phosphine complex, we examine the reaction of FeBrPh(SciOPP) 1 and bromocycloheptane employing density functional theory (DFT) calculations. Besides the cross-coupling, we also examined the competitive pathways of β-hydrogen elimination to give the corresponding alkene byproduct. The DFT study on the reaction pathways explains the cross-coupling selectivity over the elimination in terms of FeI/FeII/FeIII mechanism which involves the generation of alkyl radical intermediates and their propagation in a chain reaction manner. The present study gives insight into the detailed molecular mechanic of the cross-coupling reaction and revises the FeII/FeII mechanisms previously proposed by us and others.
