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]
Rarer than primary amines is the use of ammonia to give a primary imine. [17] ... as illustrated with benzophenone imine: [28] (C 6 H 5) 2 C=NH + CH 3 Li → ...
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 ...
Several strategies have been developed to overcome this based on reagents that serve as ammonia equivalents. The use of a benzophenone imine or silylamide can overcome this limitation, with subsequent hydrolysis furnishing the primary aniline. [37] [38] [39]

In organic chemistry, an oxime is an organic compound belonging to the imines, with the general formula RR’C=N−OH, where R is an organic side-chain and R' may be hydrogen, forming an aldoxime, or another organic group, forming a ketoxime. O-substituted oximes form a closely related family of compounds.
