Rate-enhancing multi-site interaction in the hydrolysis of a cationic ester catalysed by a Cu2+ complex of an anionic surfactant ligand in anionic sodium dodecyl sulfate micelles

Abstract

The rate of hydrolysis of 2-nitro-4-trimethylammoniophenyl 2-picolinate is remarkably enhanced when catalysed by a Cu²⁺ complex of surfactant imidazole ligand possessing 2-hydroxymethyl and anionic charged groups in the co-micelles of sodium dodecyl sulfate; the rate enhancement is discussed in terms of multi-site interaction in the formation of a reactive ternary complex.
