Description

Application

Benzaldehyde can be used as a reactant to synthesize:

• β-amino ketone derivatives by Cu nanoparticles catalyzed one-pot, three-component Mannich reaction with various aromatic ketones and amines.
• Enantioselective 1-phenyl-1-propanol by asymmetric addition of diethylzinc in the presence of fenchone-based derivatives as catalysts.
• Benzoylborane by reacting with a boryl Grignard reagent (borylmagnesium).
• Diethyl benzylidenemalonate by piperidine catalyzed reaction with diethyl malonate.
