[EN] Cationic Cu L complexes (L=Buchwald-type phosphane) with N co-ligands have been characterised by structural and spectroscopic properties. These copper(I) complexes are extremely active catalysts, far more active than analogous gold(I) complexes, to promote the single and double A3 coupling of terminal alkynes, pyrrolidine and formaldehyde. The activity data show the possible ways in
which the solvent can influence the catalytic performance by limiting complex solubility, by solvent decomposition or instability of the copper(I) redox state. Isolation of copper(I) complexes that are likely to be the key catalytic species has allowed light to be shed on the reaction mechanism
