This article reported the hydrolytic kinetics of carboxylate and phosphate esters catalyzed by the new metallomicelles formed from Cu^2^+ or Zn^2^+ and long chain ligands with alcohol hydroxyl, amino or imidazolyl groups. The results showed that the matallomicelle formed from Zn^2^+ or Cu^2^+ and N-tetradecyl-2-(N-2'-hydroxyethyl aminomethyl)-imidazol in the presence of cetyltrimethyllammonium bromide could catalyze the hydrolysis of p-nitrophenyl picolinate and react with parathion rapidly, its alcohol hydroxyl took part in the attack on p-nitrophenol acetate and p-nitrophenol diphenol phosphate. In addition, this metallomicelle showed good electrostatic selectivity to anionic carboxylic esters.
