Studies on the reaction kinetics and the mechanism of hydrolysis of bis(4-nitrophenyl) phosphate (BNPP) catalyzed by oxamido-bridged dinuclear copper(II) complexes in micellar solution

摘要

Oxamido-bridged dinuclear copper(II) complexes,used as symmeteci two-center caltalysts for the cleavage of BNPP,were synthexezed and characterized.The reaction kinetics and the mechanism of hydrolysis of BNPP catalyzed by matallomicelles,made from complex(A) or (B) an a surfactnat (LSS or CTAB),were investigated.A kinetic mathematical model for BNPP cleabage was also proposed.The results showed that the reaction rate for the catalytic hydrolysis of BNPP,compared with spontaneous hydrolysis of BNPP,increased by a factor of ca.1X10~6 study indicates that the metallomicelle-containing oxamido-bridged dinuclear copper(II) complex may be a potential catalyst for the hydrolysis of BNPP.
