摘要
A dialkylated pyridine, 3-[(A’-methyl-A’-4-pyridyi)amino]propionic acid, was attached covalently to laurylated poly(ethylenimine)s. It showed marked catalytic effects in the hydrolysis of nitrophenyl acylates. Spectrophotometric observations in the near-ultraviolet established that the hydrolysis proceeds through a nucleophilic pathway. © 1979, American Chemical Society. All rights reserved.
