The active nickel complex generated in situ by reduction of NiBr2(PPh3)2 with zinc in the presence of Et4NI is a useful reagent for the dehalogenative coupling of phenacyl halides to 1,4-diaryl-1,4-diketones and for the dechlorination of 3,4-dichlorobicyclo-octane-2,5-diones to bicyclooct-3-ene-2,5-diones.
