Assembly of the Au-diphosphine helical cage molecules via alkynyl-μ4-methylydine ligand transformation.
The assembly of the gold(I)-diphosphine cages occurs via unprecedented transformation of the alkynyls into the μ(4)-methylydine ligands under basic conditions. These compounds demonstrate the equilibrium between the P↔M helical isomers and serve as hosts to accommodate small molecules (CH(2)Cl(2) and CS(2)).
