The catalyst, when present in 2 mol % quantity in methanol solution, catalyzes the addition of hydrogen cyanide to N -alkylimines to afford α -amino nitriles in high yield and high enantiomeric excess. Furthermore, acid hydrolysis of N -benzhydryl- α -amino nitriles afforded the ...

Chemical synthesis is usually performed by the hydrolysis of lactonitrile with the use of strong acids [5]. Through this process, the racemic mixture (d- and l-lactic acid) is always obtained, while optically purer lactic acid can be produced by the biological (enzymatic) route. This ...
This was demonstrated to be an efficient catalyst for dehydration of aldoximes to nitrites. An unexpected self-induced phase separation of the reaction mixture was observed when the reaction was carried out in acetonitrile. This could be attributed to the hydrolysis of [CBMIm]SO3Cl to regenerate ...
Then sodium malonate reacts with a variety of lively halides to generate substituted malonate. Malonate can prepare various monocarboxylic acids, dicarboxylic acids, keto acids and other compounds by hydrolysis reaction to lose carboxyl. As substituted malonate reacts with urea to prepare a commonly ...
