Symmetrical and unsymmetrical conjugated diynes are chemo-, regio-, and stereoselectively carbomagnesiated with a ?Grignard reagent at room temperature in the presence of a catalytic amount of FeCl2 without the need for an external ligand. The resulting magnesium intermediate can be further functionalized to give polysubstituted 1,3-enyne derivatives. Georg Thieme Verlag Stuttgart New York.
