Hemilabile Bonding Of 1-Oxa-4,7-Dithiacyclononane In Cyclometallated Palladium(Ii) Complexes, Daron E. Janzen, Meaghan A. Bruening, A. A. Mamiya, Laura E. Driscoll, Demetrio A. De Silva Filho Jul 2019

Hemilabile Bonding Of 1-Oxa-4,7-Dithiacyclononane In Cyclometallated Palladium(Ii) Complexes, Daron E. Janzen, Meaghan A. Bruening, A. A. Mamiya, Laura E. Driscoll, Demetrio A. De Silva Filho

Daron E Janzen, Ph.D.

The synthesis and characterization of a series of cyclometallated complexes of Pd(II) incorporating the mixed donor ligand 1-oxa-4,7-dithiacyclononane ([9]aneS2O) are presented in this study. Complexes of the form [Pd(C^N)([9]aneS2O)](PF6) (C^N = 2-phenylpyridine (ppy) 1b, 4-(2-pyridyl)benzaldehyde (ppyCHO) 2b, 7,8-benzoquinoline (bzq) 3b, 2-benzothienylpyridine (btp) 4b, 2-phenylbenzothiazole (pbt) 5b), were obtained in high-yield from a simple two-step synthetic scheme. All of these complexes were fully characterized by NMR, ESI-MS, IR, combustion analyses, and most (1b, 2b, 4b, 5b) by X-ray crystallography. Solution 1H and 13C NMR studies of [Pd(C^N)([9]aneS2O)](PF6) complexes demonstrate complicated [9]aneS2O …
