N2 - The new, stable, chiral thiol-TADDOL Cu1 catalysts 1 (X = OH, OMe, NMe2) reveal an unexpected monodentate complexation mode, both in solution and in the solid state. For the first time, the aggregation state of organocopper complexes has been determined by NMR diffusion measurements NOESY NMR data on model isocyanide Cu complexes reveal a different conformation of the TADDOL moiety as a function of the second potential donor group. TADDOL = α,α,α',α'-tetraaryl-2,2-dimethyl-1,3-dioxolane-4,5- dimethanol.
