摘要: The hydrolyses of naphthalene diimides (NDIs) bearing aliphatic side chains with Nmethylpyrrolidinium groups placed two (1) and three (5) atoms from the central core were studied. Ka values for first second 1 2.5 ± 0.2 x 10 5 M 2.0 0.1 , respectively; they 1.4 44 2 respectively. NDI hydrolyzed 6.8 times faster than did 5. rates at 100 mM hydroxide measured by stopped-flow 17.0 s 53.0 NMR showed both syn anti isomers diamide species. Syntheses other derivatives are reported. Overall, this study shows that rate hydrolysis NDIs is increased when cationic charge moved closer to core. INDEX WORDS: Hydrolysis, diimide, monoimide, diamide, borate buffer.
