摘要

Abstract Nucleophilic substitution reaction of p-nitrophenyl acetate (PNPA), p- nitrophenyldiphenyl phosphinate, and pesticide parathion with different α-nucleophiles [I] have been studied at 27 C in different pH in the presence of a novel cationic surfactant. inline image The kinetic study was performed spectrophotometrically under pseudo-first order conditions with the α-nucleophile in excess. The pK a of nucleophiles have also ...
