The catalytic hydrolysis of p-nitrophenyl picolinate (PNPP) by Cu(II) and Zn(II) complexes coordinating tripeptide were studied kinetically by observing the rates of release of p-nitrophenol in the buffered micellar solution at 25 β’ C and different pH values. The experimental results indicate that 1
## Abstract Two Schiff base cobalt(II) complexes containing crowned substituents have been synthesized and employed to promote the hydrolysis of __p__βnitrophenyl picolinate (PNPP) in a buffered micellar solution formed by a cationic Gemini surfactant, bis(hexadecyldimethylammonium)hexane bromide (
The ternary complex kinetic model for metallomicellar catalysis has been proposed in this paper. The catalytic effects of bivalent metal ion (Cu(2+), Zn(2+), and Ni(2+)) complexes of long alkyl pyridine ligands upon the hydrolysis of p-nitrophenyl picolinate (PNPP) have been studied kinetically in a
