Hydrolysis of phosphodiester catalyzed by analogous dinuclear Cu(II) complex in CTAB micellar solution

摘要

The catalytic hydrolysis of bis(p-nitrophenyl) phosphate (BNPP) by metallomicelle composed of analogous Cu(11) complex in CTAB micellar solution was investigated at 30 degrees C and different pH. The results indicate that the analogous complex with 1:2 ratio of ligand to metal ion in CATB micellar solution is the active species for catalyzing the hydrolysis of BNPP. The ternary complex kinetic model for metallomicellar catalysis was employed to obtain the relative kinetic and thermodynamic parameters for taking apart the mechanism of the catalytic hydrolysis of BNPP.
