Sonication allows the efficient preparation of various organozinc reagents, which cleanly add in a conjugate fashion to α-enones in the presence of Ni(acac)2.

Diorganozinc compounds can be prepared with great ease and efficiency in a one-pot process, by sonication of lithium, an organic halide, and a zinc halide in THF or toluene mixtures.The reagents thus obtained give rise to clean and selective conjugate additions to α,β-unsaturated aldehydes and ketones in the presence of catalytic amounts of nickel acetylacetonate.
