Under typical reaction conditions, both direct and conjugate modes of addition occur rapidly. But because the reactions are reversible, they generally proceed with thermodynamic control rather than kinetic control so the more stable conjugate addition product is often obtained to the complete exclusion of the less stable direct addition product.
