Primary amines can be protected as benzophenone imines, and the protected amines are stable in flash chromatography. [7] Buchwald-Hartwig amination involves coupling aromatic halide and amine to form carbon-nitrogen bonds with the help of palladium-based catalysts. Benzophenone imine can be used as an ammonia-equivalent in such reactions. [1]

Benzophenone is a naturally occurring organic compound with the formula (C 6 H 5) 2 CO, generally abbreviated Ph 2 CO. 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 ...
When R = H, the compound is a primary imine, when R is hydrocarbyl, the compound is a secondary imine. If this group is not a hydrogen atom, then the compound can sometimes be referred to as a Schiff base. [9] When R 3 is OH, the imine is called an oxime, and when R 3 is NH 2 the imine is called a hydrazone.
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 ...
The FDA proposed a ban on phenylephrine, a common decongestant found in cold and cough medications. Here’s why and a list of medicines with phenylephrine.
The three primary enzymes in Biotène were glucose oxidase, lactoperoxidase, and lysozyme. [7] These enzymes, through their antibacterial and healing properties, create natural protection within the oral cavity, balancing and boosting an individual's salivary defenses.
