A simple and efficient catalytic arylmagnesiation of diarylacetylenes and aryl(alkyl) acetylenes is accomplished by NiCl2 center dot 6H(2)O at r.t. in the absence of stabilising ligands. The corresponding tetra-substituted alkenes can be obtained in good yields by subsequent treatment with different electrophiles.
