Abstract: | The palladacycle Pd(μ-O2CMe){κ2C,N-4-MeC6H3N(Me)NO}]2 readily undergoes bridge cleavage reactions with a variety of compounds containing donor functionalities including thioamides, 8-hydroxyquinoline, thioureas, selenoureas, acetylacetone derivatives, dithiocarbamates, xanthates, as well as bidentate N-donors to afford either the monomeric, neutral Pd(II) complexes Pd{κ2C,N-4-MeC6H3N(Me)NO}{L-L}] or the monocationic complexes Pd{κ2C,N-4-MeC6H3N(Me)NO}(N-N)]PF6 in high yields. A series of 15 different complexes was prepared and fully characterised spectroscopically and, in some cases, by X-ray diffraction. It was also found that the dithiocarbamato complex undergoes a disproportionation reaction in solution to give the bis(cyclometallated) complex Pd{κ2C,N-4-MeC6H3N(Me)NO}2] as well as the bis(dithiocarbamato) complex Pd{κ2S-S2CNEt2}2]. |
