C 6 H 5 C(CH 3) 2 O 2 H → C 6 H 5 C(O)CH 3 + CH 3 OH. The cumene process is conducted on such a large scale that even the small amount of acetophenone by-product can be recovered in commercially useful quantities. [2] Acetophenone is also generated from ethylbenzene hydroperoxide.
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]
Phenacyl chloride, also commonly known as chloroacetophenone, is a substituted acetophenone.It is a useful building block in organic chemistry.Apart from that, it has been historically used as a riot control agent, where it is designated CN. [5]
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. [2] L-malic acid is used to resolve 1-Phenylethylamine, a versatile resolving agent in its own right.
Phenacyl bromide is the organic compound with the formula C 6 H 5 C(O)CH 2 Br. This colourless solid is a powerful lachrymator as well as a useful precursor to other organic compounds. It is prepared by bromination of acetophenone: [2] C 6 H 5 C(O)CH 3 + Br 2 → C 6 H 5 C(O)CH 2 Br + HBr. The compound was first reported in 1871. [3]
The Bischler–Möhlau indole synthesis, also often referred to as the Bischler indole synthesis, [1] is a chemical reaction that forms a 2-aryl-indole from an α-bromo-acetophenone and excess aniline; it is named after August Bischler and Richard Möhlau [].
Cumene hydroperoxide is the organic compound with the formula C 6 H 5 C(CH 3) 2 OOH; this oily liquid is classified as an organic hydroperoxide. [2] 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.
Acetone oxime (acetoxime) is the organic compound with the formula (CH 3) 2 CNOH. It is the simplest example of a ketoxime.It is a white crystalline solid that is soluble in water, ethanol, ether, chloroform, and ligroin.
