Diversity in Bonding of Dithiadibenzo[24]crown Ether. Reversible Formation of Pseudorotaxane of Dibenzylammonium and Complexation with PdCl2
[2]Pseudorotaxane of dibenzylammonium and dithia[24]-crown-8-ether (DTC) reacts with [PdCl2(cod)] (cod: 1,5-cyclooctadiene) to form [PdCl2(DTC)], accompanied by liberation of dibenzylammonium and cod. Further addition of PPh3 to the mixture causes formation of [PdCl2(PPh3)(2)] and regeneration of the [2]pseudorotaxane.
