Reactivity Of Dimethylplatinum(Ii) Complexes With Peroxides, Kyle R. Pellarin
Reactivity Of Dimethylplatinum(Ii) Complexes With Peroxides, Kyle R. Pellarin
Electronic Thesis and Dissertation Repository
This thesis describes a study of dimethylplatinum(II) complexes containing bidentate nitrogen donor ligands. This work deals with the oxidative addition of peroxides and focuses on synthesis, characterization and reaction mechanisms of these complexes.
Dimethylplatinum(II) complexes were reacted with oxidants dimethyldioxirane (DMDO), meta-chloroperbenzoic acid (m-CPBA) and phthaloyl peroxide. The use of these oxidants has allowed for the synthesis of novel platinum(IV) complexes by oxidative addition and the formation of unique supramolecular networks. The formation of both trans- and cis-oxidative addition products was controlled by the type of oxidant utilized. By varying the ligand design of the …
Reactions Of Platinum Complexes With Dimethylamine-Borane, Shawn M. Robinson
Reactions Of Platinum Complexes With Dimethylamine-Borane, Shawn M. Robinson
Electronic Thesis and Dissertation Repository
This thesis describes a study of the reactions of platinum complexes with dimethylamine-borane (DMAB) as models for alkane activation. It is concluded that sigma-borane complexes of platinum(II) or platinum(IV) will be difficult to synthesize or even to detect as intermediates in hydride transfer from boranes to platinum.
The complex [PtMe(O2CCF3)(bpy)] reacts with DMAB to form an intermediate [PtMeH(bpy)] complex, which undergoes reductive elimination of methane with further degradation to give platinum(0) and free 2,2’-bipyridine. The addition of methyl acrylate to the reaction allowed the trapping of the platinum-hydride, producing [PtCl(CHMeCO2Me)(bpy)] and [Pt(CHMeCO2Me) …
