  • Pseudo-first-order rate constants (kobs) for the reaction of N-benzylphthalimide (NBPT) with HO- have been determined at 2.0 × 10?4 M NBPT, 1.0 × 10?3 and 2.0 × 10?3 M NaOH as well as varying concentrations of cetyltrimethylammonium bromide ([CTABr]T = 0.0-1.7 × 10?1 M). The effects of [CTABr]T ? CMC (with CMC representing the critical micelle concentration of CTABr) on kobs have been analyzed in terms of Berezin's pseudophase (BPP) model and pseudophase ion-exchange (PIE) model. Although both models give the best observed data fit with least-squares values not significantly different from each other, the calculated values of KS from BPP model appear to be more reliable compared to those from PIE model because the values of KS from BPP model are similar to the corresponding KS values determined spectrophotometrically.

  • $\alpha$-Functionalized benzylamine(Nu=OAc, OMe, $N_3$)은 유기합성의 출발물질 또는 synthon으로서 매우 유용할 것이다. 본 연구에서는 benzylphthalimide를 137$^{\circ}C$, chlorobenzene 용매 하에서 NBS/NaOAc/HOAc조건을 사용하여, 높은 수율로 phthalimide-benzyl acetate을 얻는 방법을 개발하였다. 마지막으로, phthalimide-benzyl acetate을 $NH_2NH_2$/HOAc 조건 하에서, amino(phenyl)methyl acetate (1)을 합성하였다.
