Abstract

Study of the kinetics of alkaline hydrolysis of alkylp-nitrophenyl chloromethylphosphonates in micellar solutions of cetylpyridinium bromide showed that the observed rate constant depends on the hydrophobicity of the substrates. A minor increase in the length of the alkyl chain in the substituent increases the catalytic effect in the series Et<Bu<C6H13. Further increase in the substrate hydrophobicity results in a decrease in the bimolecular rate constant in the micellar phase.
