Acylcuprates obtained by carbonylation of R(CN)CuLi cuprates (R = t-Bu, sec-Bu) at low temperature are effective in the directnucleophilic1,4-acylation of α,β-unsaturated ketones and aldehydes. The R = t-Bu reagent is sufficiently stable so that it can be used even at room temparature. The R = sec-Bu reagent is best used at −110°C.
