4,4’-Dichlorobenzophenone is prepared by the acylation of chlorobenzene with 4-chlorobenzoyl chloride. The conversion is typically conducted in the presence of an aluminium chloride catalyst in a petroleum ether solvent. ClC 6 H 5 C(O)Cl + C 6 H 5 Cl → (ClC 6 H 4) 2 CO + HCl
4-Fluorobromobenzene is synthesized via bromination of fluorobenzene in the presence of a Lewis acid catalyst such as iron(III) bromide or aluminium tribromide. [2]4-Bromofluorobenzene is regarded by the Toxic Substances Control Act as a high production volume chemical, that is, a chemical that 1 million pounds (about 500 tonnes) per year is either produced in or imported to the United States.
4,4’-Difluorobenzophenone is an organic compound with the formula of (FC 6 H 4) 2 CO. This colorless solid is commonly used as a precursor to PEEK, or polyetherether ketone, a so-called high performance polymer. Because PEEK is resistant to attack, it is commonly used in carbon fiber coatings and cable insulation.
Lorazepam can be made using 2-amino-2′,5-dichlorobenzophenone (a derivative of 2-amino-5-chlorobenzophenone), which is first reacted with hydroxylamine, the obtained product is then reacted with chloroacetyl chloride to give 6-chloro-2-chlormethyl-4-(2′-chlorophenyl)quinazolin-3-oxide, a reaction with methylamine produces ring expansion and rearrangement, which forms 7-chloro-2-methylamino ...
4-Chloro-alpha-Pyrrolidinohexiophenone (4-Cl-PHP) is a substituted cathinone derivative with stimulant effects, which has been sold as a designer drug.It was first officially identified by forensic laboratories in 2016, though anecdotal reports suggest it may have been available several years prior to this.

4-Chloro-α-pyrrolidinovalerophenone (also known as 4-chloro-α-pyrrolidinopentiophenone, 4-chloro-α-PVP, 4Cl-PVP, or 4C-PVP, or alpha-PVP, or flakka) is an emerging recreational designer drug of the pyrrolidinophenone class, similar in structure to α-pyrrolidinopentiophenone (α-PVP). [1]
Benzophenone has been found in some fungi, fruits and plants, including grapes. [4] It is a white solid with a low melting point and rose-like odor [5] that is soluble in organic solvents. Benzophenone is the simplest diaromatic ketone. It is a widely used building block in organic chemistry, being the parent diarylketone. [citation needed]
