LiBF4‐Induced Rearrangement and Desymmetrization of a Palladium‐Ligand Assembly

Kay Severin, Rosario Scopelliti, Sylvain Alexandre Marie Sudan, Farzaneh Fadaei Tirani

Thirteen palladium-ligand assemblies with different structures and topologies were investigated for the ability to bind lithium ions. In one case, the addition of LiBF4 resulted in a profound structural rearrangement, converting a dincluclear [Pd2L4]2 comp ...
