Abstract:
Two dipalladium complexes [(bpy)(2)Pd-2(NO3)(2)](NO3)(2), [(dmbpy)(2)Pd-2(NO3)(2)](NO3)(2) (bpy=2,2-bipyridine, dmbpy=4,4' -dimethyl-2,2-bipyridine) were used as"clips"to coordinate with ditopic pyrazolate ligands (HL1, HL2), leading to the formation of [Pd2L2](2-) -type dinuclear coordination"clips"with strong intramolecular Pd(II)center dot center dot center dot Pd(II) bonding interaction through a spontaneous deprotonation of the pyrazole ligands in aqueous solution. Such well-defined complexes C1 similar to C4 have been characterized by single-crystal X-ray diffraction analysis, elemental analysis, H-1 and C-13 NMR, electrospray ionization mass spectrometry (ESI-MS) and IR spectroscopy. Furthermore, all these clip-like dipalladium(II) complexes exhibited highly catalytic activities towards Suzuki-coupling reaction under mild conditions. CCDC: 2060495, C1 center dot 2NO(3)(-).
