Hydrolysis rate of two types of compounds, A and B were studied in the presence of variable concentrations of an anionic surfactant (sodium dodecylsulfate, SDS). Class A of compounds consists of substances which hydrolyze by the SN1 mechanism and which are structurally related to cationic surfactants. The second class (B) contains an internal nucleophile and thus solvolyzes under anchimeric assistance. It was found that ...
