Abstract

The micellization and catalytic properties of the diquaternary 1,4-diazabicyclo[2.2.2]octane derivatives, viz., 1-alkyl-4-ethyl-1,4-diazoniabicyclo[2.2.2]octane dibromides (DAD) in water were studied by conductometry, viscosimetry, and spectrophotometry. The critical micelle concentrations and the semiaxial ratio of the micellar aggregates were determined. The character and strength of the effect of the DAD micelles on the alkaline hydrolysis of 4-nitrophenyl alkylchloromethylphosphonates depend on the surfactant and substrate structures, DAD concentration in solution, and temperature. An increase in the hydrophobicity of DAD and phosphonate increases the efficiency of catalysis.
