Acetophenone is the organic compound with the formula C 6 H 5 C(O)CH 3. It is the simplest aromatic ketone . This colorless, viscous liquid is a precursor to useful resins and fragrances.
1-Phenylethylamine may be prepared by the reductive amination of acetophenone: [1]. C 6 H 5 C(O)CH 3 + NH 3 + H 2 → C 6 H 5 CH(NH 2)CH 3 + H 2 O. The Leuckart reaction, using ammonium formate, is another method for this transformation.
Phenylacetone, also known as phenyl-2-propanone, is an organic compound with the chemical formula C 6 H 5 CH 2 COCH 3. It is a colorless oil that is soluble in organic solvents. It is a mono-substituted benzene derivative, consisting of an acetone attached to a phenyl group. As such, its systematic IUPAC name is 1-phenyl-2-propanone.
Phenylglyoxal was first prepared by thermal decomposition of the sulfite derivative of the oxime: [5]. C 6 H 5 C(O)CH(NOSO 2 H) + 2 H 2 O → C 6 H 5 C(O)CHO + NH 4 HSO 4. More conveniently, it can be prepared from methyl benzoate by reaction with KCH 2 S(O)CH 3 to give PhC(O)CH(SCH 3)(OH), which is oxidized with copper(II) acetate. [6]
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.
Propiophenone can be prepared by Friedel–Crafts reaction of propanoyl chloride and benzene.It is also prepared commercially by ketonization of benzoic acid and propionic acid over calcium acetate and alumina at 450–550 °C: [1]
It is a colourless, fuming liquid with an irritating odour, and consists of a benzene ring (C 6 H 6) with an acyl chloride (−C(=O)Cl) substituent. It is mainly useful for the production of peroxides but is generally useful in other areas such as in the preparation of dyes , perfumes , pharmaceuticals , and resins .
Products of decomposition of cumene hydroperoxide are methylstyrene, acetophenone, and 2-phenylpropan-2-ol. [3] It is produced by treatment of cumene with oxygen, an autoxidation. At temperatures >100 °C, oxygen is passed through liquid cumene: [4] C 6 H 5 CH(CH 3) 2 + O 2 → C 6 H 5 C(CH 3) 2 OOH. Dicumyl peroxide is a side product.
