Benzophenone imine is an organic compound with the formula of (C 6 H 5) 2 C=NH. A pale yellow liquid, benzophenone imine is used as a reagent in organic synthesis. [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 ...
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]
The Forster–Decker method is a series of chemical reactions that have the effect of mono-alkylating a primary amine (1), forming a secondary amine (6). [1] [2] The process occurs by way of transient formation of an imine (3) that undergoes the actual alkylation reaction.
This method is known as Moureu-Mignonac ketimine synthesis. [19] [20] [21] For example, benzophenone imine can also be synthesized by addition of phenylmagnesium bromide to benzonitrile followed by careful hydrolysis (lest the imine be hydrolyzed): [22] C 6 H 5 CN + C 6 H 5 MgBr → (C 6 H 5) 2 C=NMgBr (C 6 H 5) 2 C=NMgBr + H 2 O → (C 6 H 5 ...
The Stetter reaction is a reaction used in organic chemistry to form carbon-carbon bonds through a 1,4-addition reaction utilizing a nucleophilic catalyst. [1] While the related 1,2-addition reaction, the benzoin condensation, was known since the 1830s, the Stetter reaction was not reported until 1973 by Dr. Hermann Stetter. [2]
The Beckmann rearrangement, named after the German chemist Ernst Otto Beckmann (1853–1923), is a rearrangement of an oxime functional group to substituted amides. [1] [2] The rearrangement has also been successfully performed on haloimines and nitrones.
Pigment Yellow 97, a popular yellow colorant, is a hydrazone. [6]Hydrazones are the basis for various analyses of ketones and aldehydes. For example, dinitrophenylhydrazine coated onto a silica sorbent is the basis of an adsorption cartridge.
