it is p ossible to control, to a high degree, the regiochemical outcome of nickel(0)-catalysed hydrocyanations of alk-1-ynes: the crystal structure of one adduct is included which establishes that the stereochemical outcome of the reaction is a result of addition of HCN to the alkyne to give an (E)-product; overall, these results constitute a simple method for the preparation of (E)-2-alkyl-3-trialk
