Mixing an enone, zinc powder, TMEDA, and an alkyl halide in an aqueous micellar environement containing catalytic amounts of Cu(I) and Au(III) enables conjugate additions in water at room temperature via in situ generated organocopper reagents in good yields. In the presence of Ag(I), the amounts of alkyl halide, Zn, and AuCl3 can be reduced dramatically.
