Application

Benzaldehyde may be used as a reference standard for the determination of benzaldehyde, the toxic oxidation product of benzyl alcohol used as a preservative in injectable formulations of the non-steroidal anti-inflammatory drugs, diclofenac, and piroxicam, and in vitamin B-complex injection solutions by capillary gas chromatography.

Benzaldehyde, with its apricot and almond-like aroma, is the second most abundantly used molecule in the flavor industry, and is most commonly produced via chemical routes, such as by the oxidation of toluene. Biologically produced benzaldehyde, whether by extraction of...

We previously reported the novel efficient proton/heat-promoted four-component reactions (4CRs) of but-2-ynedioates, two same/different primary amines, and aldehydes for the synthesis of tetra- and pentasubstituted polyfunctional dihydropyrroles. If aromatic and aliphatic amines were used as reagents, four different series of...

A one-pot transition-metal-free, base-mediated synthesis of dibenzo[b,f]oxepins was developed. The reaction of 2-halobenzaldehydes with (2-hydroxyphenyl)acetonitriles proceeds via a sequential aldol condensation and intramolecular ether formation reaction in the presence of Cs(2)CO(3) and molecular sieves in toluene.
