Cationic Copper(I) Complexes as Highly Efficient Catalysts for Single and Double A super(3)-Coupling Mannich Reactions of Terminal Alkynes: Mechanistic Insights and Comparative Studies with Analogous Gold(I) Complexes

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 A super(3) coupling... Full description

description: 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 A super(3) 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. Better than gold: Cationic copper-L complexes (L=Buchwald-type phosphane) with nitrogen co-ligands are extremely active homogenous catalysts; far more active than analogous gold(I) complexes at promoting the mono- and bis-Mannich A super(3)-coupling reactions (see scheme). Isolation of...
