摘要: The syntheses of two novel o-carboranyl palladium complexes [PdClMe(1,2-(PPh 2 ) -1,2-C B 1 0 H )] and [PdClMe(1,2-(P i Pr are described their crystal structures determined. Both were obtained in CH Cl by methods: (i) replacement 1,5-cyclooctadiene (cod) [PdClMe(cod)] 1,2-(PPh 1,2-(P (ii) the reaction [PdCl (1,2-(PR (R = Ph, Pr) with SnMe 4 . In both carborane cage is co-ordinated bidentately through P atoms to Pd(II) ion, while ion Me group cis positions complete distorted square-planar co-ordination around metal. Differences "P-NMR spectra PdCl diphosphines organic ethane benzene backbones discussed. 3 P-NMR have been compared other having same metal surrounding. data allowed an interpretation electronic characteristics o-carborane influence these on capacity.
