Rapid hydrozirconation of alkenes by zirconocene hydrochloride, followed by addition of 1 equiv of enone and catalytic amounts of Cu(I) salts, led to the corresponding 1,4-addition products in moderate to high yields and provided the first protocol for in situ preparation of alkyl cuprates from alkenes.
