Symmetrical and unsymmetrical dizinc complexes as models for the active sites of hydrolytic enzymes.
نویسندگان
چکیده
Dinuclear carboxylate-bridged zinc complexes of one symmetric and one asymmetric phenolate-based ligand catalyse the transesterification of 2-hydroxypropyl-p-nitrophenyl phosphate (HPNP) at different rates, with an unsymmetrical complex being more active than a symmetric one.
