The use of alkenyllithium reagents is one of the most common for the preparation of alkenylcuprates. In general, the cuprate is prepared by the addition of 2 equivalents of the alkenyllithium reagent to a copper source, commonly a copper(I) halide, at low temperature in an ethereal solvent. The cuprate is then used in a subsequent reaction.
