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 initial product is a thioamide for example that of acetophenone [7] which can again be hydrolyzed to the amide. The reaction is named after Karl Kindler The Kindler modification of the Willgerodt rearrangement. A possible reaction mechanism for the Kindler variation is depicted below: [8]
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 [].

The Leuckart reaction is the chemical reaction that converts aldehydes or ketones to amines. The reaction is an example of reductive amination. [1] The reaction, named after Rudolf Leuckart, uses either ammonium formate or formamide as the nitrogen donor and reducing agent. It requires high temperatures, usually between 120 and 130 °C; for the ...
Enantioselective ketone reductions convert prochiral ketones into chiral, non-racemic alcohols and are used heavily for the synthesis of stereodefined alcohols. [1]Carbonyl reduction, the net addition of H 2 across a carbon-oxygen double bond, is an important way to prepare alcohols.
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]
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]
