Organocopper reagents have found wide use in synthetic organic chemistry during the past few decades. Structural elucidation has not yet received much attention in organocopper chemistry and the aggregation of most products is unknown. This last volume brings to an end the series of organocopper compounds and contains an Empirical Formula and Ligand Formula Index for about 3000 organocopper compounds and reagents described in Parts 1 to 4.
