The syn addition of alkylcopper compounds to various alkynes HCC(CH2)2Z (n = 2, 3, Z = X, NEt2, SEt, OR) shows a regio-selectivity dependant on various factors, the major factors being the nature of the function and the solvent. The vinylcopper derivatives thus obtained have been carboxylated, iodinated and alkylated.
