title: Synthesis of halogeno, pseudohalogeno, and carboxylatopalladium(IV) complexes by halogen exchange. Crystal structure of azido(2,2’-bipyridyl)benzylpalladium( II), formed on reductive elimination of ethane from Pd(N3)Me2(CH2Ph)(bpy) creator: Canty, AJ creator: Traill, PR creator: Skelton, BW creator: White, AH subject: 259901 Organometallic Chemistry description: The first examples of fluoro, pseudohalogeno, and carboxylatopalladium(IV) complexes have been obtained by the exchange of the bromo ligand in PdBrMe2(CH2Ph)(bpy) (bpy = 2,2’-bipyridyl) on addition of a silver salt, or silver nitrate and the appropriate anion, in acetonitrile. The syntheses have permitted a study of the effect of groups X on the selectivity in reductive elimination of ethane and ethylbenzene from PdXMe2(CH2Ph)(bpy). For X = Br, N3, SCN, or O2CPh, reductive elimination from the unstable palladium(IV) complexes in acetone gives ethane and PdX(CH2Ph)(bpy) only, but these products together with ca. 10% of ethylbenxene and PdXMe(bpy) are formed from the complexes PdXMe2(CH2Ph)(bpy) (X = F, Cl, I, OCN, SeCN, O2CCF3). The binding mode of the ambidentate pseudohalides OCN-, SCN- and SeCN- has not been determined. date: 1992 type: Article type: PeerReviewed format: application/pdf identifier: http://eprints.utas.edu.au/2955/1/JOMC1992_2C_213.pdf relation: http://dx.doi.org/10.1016/0022-328X(92)80143-L identifier: Canty, AJ and Traill, PR and Skelton, BW and White, AH (1992) Synthesis of halogeno, pseudohalogeno, and carboxylatopalladium(IV) complexes by halogen exchange.
