employed in cross-coupling reactions to yield arylated 4-amino[2.2]paracyclophanes. The amines were converted into enantiopure planar-chiralthioureas, which are potential hydrogen-bond donors for enantioselective organocatalysis. thiourea - hydrogen-bond donor - planar-chiral - cross-coupling

The synthesis of three planarchiral pseudo-gem disubstituted [2.2]paracyclophane-derived P,N-pre-ligands is reported along with preliminary results of their activity in the amination of aryl bromides and chlorides. The pseudo-gem aminophosphines were capable of mediating the coupling reaction at a loading of 1 mol%.
