## Abstract Hydrolysis of nitrophenyl caproate by modified poly(ethylenimine)s containing imidazole moieties is markedly enhanced in the presence of divalent metal ions. The order of effectiveness is Cu(II) > Co(II) > Zn(II) > Ni(II) > Mn(II), with Cu increasing the rate about 20โ€fold. The accelera
