Reactivity in micelles - are we really able to design micellar catalysts?

Original language description

Coordination of lipophilic alkyl pyridin-2-yl ketoximes 1 to Ni2+ ions, reduction of lipophilic 3-alkoxyacetophenones 2 with sodium borohydride, and alkaline hydrolysis of 4-nitrophenyl diphenyl phosphate (PNPDPP) were employed as probes in the investigation which factors may influence the reactivity of organic compounds in micellar systems. In all these reactions, a lipophilic substrate solubilized in micellar core was attacked by a hydrophilic reagent from the bulk aqueous phase. To evaluate the contribution of electrostatic interactions between the micellar surface charge and the reagent to the observed reactivity, we combined reactions involving the reagents with opposite polarity (Ni2+ cations and borohydride or hydroxide anions) with positively charged micelles of hexadecyltrimethylammonium chloride (CTAC) or bromide (CTAB) and negatively charged micelles of sodium dodecyl sulfate (SDS). Non-ionic micelles (Triton X-100 or Brij 35) served as a reference. The results of the kineti

Czech description

Koordinace lipofilních alkyl(pyridin-2-yl)ketoximů k Ni2+ iontům, redukce lipofilních 3-alkoxyacetofenonů tetrahydroboritanem sodným a alkalická hydrolýza 4-nitrofenyl-difenylfosfátu (PNPDPP) byly použity jako sondy při studiu faktorů ovlivňujících reaktivitu organických molekul v micelárních prostředích.
