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.
现在可以在室温下使用原位生成的有机铜试剂在水中完成与烯酮的共轭加成反应。在含有催化量的 Cu(I)、Ag(I) 和 Au(III) 的胶束环境中混合烯酮、锌粉、TMEDA 和卤代烷,以良好的分离产率生成 1,4-加合物:无有机金属需要形成前体。
