설명

일반 설명

Benzaldehyde is an aromatic aldehyde. Rotational transitions in benzaldehyde have been explained based on its microwave absorption spectrum. The conversion of benzaldehyde into reduced compounds in the presence of metal oxides has been studied. SmFeO₃ (perovskite-type oxide catalyst) catalyzed cyanosilylation reaction of benzaldehyde with trimethylsilyl cyanide (TMSCN) has been reported.

애플리케이션

Benzaldehyde has been used as a standard in the quantification of Achillea ligustica essential oil by GC-MS (Gas Chromatography-Mass Spectrometry).

Benzaldehyde may be used in the following studies:

• Preparation of optically active 1-phenylpropan-1-ol.
• Synthesis of meso-tetraphenylporphins and chlorins.
• As a test compound to study oxidative amidation reaction of aliphatic primary/secondary amines using N-heterocyclic carbine as a catalyst.
• Synthesis of 2-phenyl-2,3-dihydro-4H-pyran-4-one with high enantioselectivity by hetero-Diels-Alder (HDA) reaction with Danishefsky′s diene.
