  Zinc complexes of a new N3O ligand and their biomimetic reactions

  摘要：

  The new N3O ligand 2-(pyridylmethylamino)-3-(3,5-dimethylpyrazol-1-yl)-propionic acid (L1H) was synthesized and converted to L1Zn-Cl and L1Zn-Br. These complexes are tetrameric in the solid state with bridging carboxylate functions. The reaction of deprotonated L1H with zinc nitrate or zinc perchlorate yielded the aqua complexes [L1Zn-OH2] X with X = ClO4- and NO3-, which crystallize as carboxylate-bridged dimers. Their deprotonation produced, in situ, the hydroxide complex L1Zn-OH, which acted as a base toward p-nitrophenol and bis(p-nitrophenyl)phosphoric acid resulting in L1Zn-ONit and L1Zn-OPO(ONit)(2). Tris(p-nitrophenyl)phosphate was cleaved hydrolytically by L1Zn-OH, releasing one p-nitrophenyl group. A kinetic investigation of this cleavage reaction under pseudo-first-order conditions has yielded second-order rate constants k" of 0.9 s(-1) M-1 in 50% aqueous DMSO and 4.0 s(-1) M-1 in 75% aqueous DMSO.
