The original Betti base synthesized from 2-naphthol and the imine produced from the reaction of benzaldehyde and ammonia. The product of the Betti reaction is called the Betti base. The stereochemistry of the base was resolved into two isomers by using tartaric acid. Uses for the Betti base and its derivatives include: [1] [3] [4]
It is one of three isomeric monochlorinated benzaldehyde. 3-Chlorobenzaldehyde and 4-chlorobenzaldehyde are the other isomers. Whereas benzaldehyde is prone to autoxidation, the 2-chloro derivatives are more air-stable.
They can be considered as brominated derivatives of benzaldehyde, or as formylated derivatives of bromobenzene. Bromobenzaldehyde isomers Common name and systematic name
2-Carboxybenzaldehyde is a chemical compound.It consists of a benzene ring, with an aldehyde and a carboxylic acid as substituents that are ortho to each other. The compound exhibits ring–chain tautomerism: the two substituents can react with each other to form 3-hydroxyphthalide, a cyclic lactol.
Chalcone is usually prepared by an aldol condensation between benzaldehyde and acetophenone. [ 6 ] This reaction, which can be carried out without any solvent, is so reliable that it is often given as an example of green chemistry in undergraduate education.
4‑Hydroxybenzaldehyde (para‑hydroxybenzaldehyde) is an organic compound with the formula C 6 H 4 OH(CHO). [ 4 ] [ 5 ] Along with 2-hydroxybenzaldehyde and 3-hydroxybenzaldehyde , it is one of the three isomers of hydroxybenzaldehyde .
