How do I convert benzonitrile to acetophenone?
– Benzonitrile is first treated with Grignard reagent (CH3MgBr) in presence of dry ether that gives addition product which on acidic hydrolysis yields acetophenone.
What is the structure of benzonitrile?
C7H5N
Benzonitrile/Formula
How is benzonitrile formed?
Production. It is prepared by ammoxidation of toluene, that is its reaction with ammonia and oxygen (or air) at 400 to 450 °C (752 to 842 °F). In the laboratory it can be prepared by the dehydration of benzamide or by the Rosenmund–von Braun reaction using cuprous cyanide or NaCN/DMSO and bromobenzene.
How is aniline converted to benzonitrile?
(a) Conversion of Aniline to benzonitrile: Aniline is converted to benzonitrile by diazotization reaction followed by Sandmeyer reaction.
How is benzophenone prepared from benzonitrile?
-Benzonitrile reacts with phenyl magnesium bromide in presence of dry ether to give an imine complex which on acid hydrolysis gives benzophenone. Benzophenone can also be prepared by Friedel-Crafts acylation of benzene with benzoyl chloride in the presence of a Lewis acid.
What is benzonitrile used for?
Benzonitrile is used as an intermediate for rubber chemicals and as a solvent for nitrile rubber, specialty lacquers, many resins, polymers and for many anhydrous metallic salts (HSDB 1988; Hawley 1981). It is principally used as an intermediate for benzoguanamine (HSDB 1988).
What is the common name of benzonitrile?
The common name for benzonitrile is Cyanobenzene or phenyl cyanide.
Which reaction is most convenient to aniline to Benzonitrile?
-Benzene diazonium chloride is formed when aniline is treated with NaNO2 and HCl, which is then reacted with CuCN/KCN to replace N2Cl with CN, which is called as Sandmeyer’s Reaction and forms Benzonitrile.
What is Benzonitrile used for?
How will you convert benzonitrile to benzoic acid?
Benzonitrile is converted to benzoic acid by basic hydrolysis. When benzonitrile is heated with aqueous sodium hydroxide solution, it liberates ammonia gas and converts to sodium benzoate which on acidification gives benzoic acid.
