- Quantitative formation of [2]catenanes using copper(I) and palladium(II) as templating and assembling centers: The entwining route and the threading approach
-
Transition metal-mediated templating and self-assembly have shown powerful potentials for the synthesis of interlocked molecules. These two strategies were combined in designing and preparing a new type of coordination catenanes incorporating Cu(I) and Pd(II) metal centers. The ligand designed here contains a phenanthroline core and pyridine sidearms (compound 1). Using this phenanthroline-pyridine conjugated ligand, two approaches were examined, which were shown to be surprisingly efficient for the catenane synthesis: the entwining route (entwining of two ligands around Cu(I) followed by Pd(II) clipping) and the threading approach (Cu(I)-templated threading of a cyclic ligand on an acyclic ligand followed by the PD(II) clipping of the second ring). In the former method, stepwise treatment of 1 with Cu(CH3CN)4PF6 (templating center) and enPd(NO3)2 (assembling center) gives rise to the quantitative formation of CuPd2 catenane 18. In the latter method, Cu(I) templates the threading of phenanthroline-containing macrocycle 2 on ligand 1, which is followed by Pd(II) clipping to give hetero catenane 20. In both approaches, the formation of catenanes is convincing thanks to the strong templating effect of Cu(I), while the ring closure steps are efficiently furnished by Pd(II)-directed self-assembly.

- Synthesis of unsymmetrical 2,8- and 2,9-dihalo-1,10-phenanthrolines and derivatives
-
A general method for the preparation of the unsymmetrical 2,8- and 2,9- dihalophenanthrolines is presented. The use of these halophenanthrolines as synthetic substrates in the Suzuki and Sonogashira/Castro-Stevens palladium catalyzed chemistry is exemplifed. The derivatized phenanthrolines are seen as key building blocks for the design and construction of topologically complex polynuclear metal coordination complexes.
