Conjugate addition reactions to enones can now be done in water at room temperature with in situ generated organocopper reagents. Mixing an enone, zinc powder, TMEDA, and an alkyl halide in a micellar environemnt containing catalytic amounts of Cu(I), Ag(I), and Au(III) leads to 1,4-adducts in good isolated yields: no organometallic precursor need be formed.
烯酮的共轭加成反应现在可以在室温下的水中进行,使用原位生成的有机铜试剂。将烯酮、锌粉、TMEDA 和卤代烷混合在含有催化量的 Cu(I)、Ag(I) 和 Au(III)的胶束环境中,可得到良好收率的 1,4-加成产物:无需形成有机金属前体。
