Synthesis and Structures of Ti-Pd Heterobimetallic Complexes

Article abstract of DOI:10.1002/ejic.201501003

Heterobimetallic complexes containing titanium and palladium were prepared from O,N,O-N,N multidentate ligands. The ligands each contained an O,N,O-tridentate part based on a 2,6-lutidine scaffold and an N,N-bidentate di(pyridin-2-yl) part. The O,N,O-moiety selectively coordinated to a titanium atom on treatment with titanium(tetraisopropoxide), although one of the di(pyridin-2-yl) groups in the N,N-moiety coordinated to the titanium atom. The N,N-bidentate di(pyridin-2-yl) moiety coordinated to the palladium atom on treatment with bis(benzonitrile)palladium(II) chloride to afford a heterobimetallic complex. The dynamic behavior of the complexes in solution was studied by NMR spectroscopy. Heterobimetallic complexes containing titanium and palladium were prepared from O,N,O-N,N multidentate ligands and structurally characterized.
