Organocopper(I) reagents, RCu, are both more stable and more reactive when prepared in dimethyl sulfide instead of ether or tetrahydrofuran. A wide range of Li reagents has been investigated with good results, as has a selection of Grignard reagents. Excellent yields of products are observed with typical substrates such as α,β-unsaturated ketones and acid chlorides.

有机铜(I)试剂RCu既更稳定,也更具反应性。已经研究了多种Li试剂,以及精选的Grignard试剂,均取得了良好的效果。使用典型的底物,例如α,β-不饱和酮和酰
氯,可以观察到极好的产品收率。
