RESUMO
A reação de substituição entre cianocupratos de ordem inferior e teluretos vinílicos funcionalizados Z foi estudada. Cetonas cíclicas alfa,beta-insaturadas foram obtidas em excelentes rendimentos. Mudanças nas condições da reação forneceram ésters alfa,beta-insaturados com alta diastereosseletividade.
