NaY Zeolite: A Useful Catalyst for Nitrile Hydrolysis

open access: yesMolecules, 2000
The NaY zeolite catalysed hydrolysis of nitriles to primary amides is reported. It is found that aryl nitriles with strong electron-withdrawing substituents and cyanopyridines are readily hydrolysed in the water suspension, while aliphatic nitriles do ...
