摘要
The dinuclear palladium diselenolenes, [Pd-2(Se2CnH2n-4)(2)(PR3)(2)] react with haloalkanes, via electrophilic attack at the bridging selenium, atoms, to yield the neutral mononuclear square planar palladium(II) complexes, [PdX(Se{R'}CnH2n-4Se)(PR3)] (n = 6, 7, 8; R= Ph, Bu; X = Br; I; R' =Me, Et, etc.), containing a novel chelating selenolato/selenide ligand, in which the alkylated selenium and halogen donor atoms occupy cis-positions. The products have been characterised by mass spectrometry and multinuclear NMR spectroscopy; the molecular structure of the compound with n = 8, R = Ph, R' = Et has been determined by X-ray crystallography.
