Acetophenone is formed as a byproduct of the cumene process, the industrial route for the synthesis of phenol and acetone.In the Hock rearrangement of isopropylbenzene hydroperoxide, migration of a methyl group rather than the phenyl group gives acetophenone and methanol as a result of an alternate rearrangement of the intermediate:
The reaction of acetophenone enolate with phenyl isothiocyanate. In this one-pot synthesis [9] the ultimate reaction product is a Thiazolidine. This reaction is stereoselective with the formation of the Z-isomer only. Electrochemical reduction gives thioformamides. [10]: 340
First stage of Hock process: alkylation of benzene with propylene. Second stage of Hock process: autoxidation of cumene. The cumene process (cumene-phenol process, Hock process) is an industrial process for synthesizing phenol and acetone from benzene and propylene.
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.
The chemical modifies peptides, both at α- or ε-amino groups, and in a poorly understood but rapid modification of certain glycine residues. [73] In pathology, acetone helps find lymph nodes in fatty tissues (such as the mesentery) for tumor staging. [74] The liquid dissolves the fat and hardens the nodes, making them easier to find. [75]
Chemical formula. C 8 H 7 Br O: Molar mass: 199.047 g·mol −1 Appearance ... It is prepared by bromination of acetophenone: [2] C 6 H 5 C(O)CH 3 + Br 2 → C 6 H 5 ...
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.
