Highly reactive zero valent copperderivedfrom a CuCN·2LiCl complex reacts directly with 2,3-dichloropropene to yield a new bia-organocopper species containing both a nucleophilic allylic and vinylic moiety. This new bis-ogranocopper reagent undergoes selective one-pot addition to two different electrophiles in good to excellent yields.
