Article abstract of DOI:10.1021/jo00339a016

The reduction of NiBr2*2DME by means of potassium-graphite affords highly dispersed nickel on the graphite surface (Ni-Gr1).Freshly prepared Ni-Gr1 is used "in situ" as a catalyst for semihydrogenation of alkynes to alkenes in the presence of ethylenediamine as catalyst modifier.Unconjugated and conjugated (Z)-alkenes with a stereospecificity of 96-99percent and 94percent, respectively, are obtained.
