Benzamide is an organic compound with the chemical formula of C 7 H 7 NO. It is the simplest amide derivative of benzoic acid . In powdered form, it appears as a white solid, while in crystalline form, it appears as colourless crystals. [ 5 ]
Benzonitrile is a useful solvent and a versatile precursor to many derivatives. It reacts with amines to afford N-substituted benzamides after hydrolysis. [3] It is a precursor to diphenylmethanimine via reaction with phenylmagnesium bromide followed by methanolysis.
Benzimidazole is a base: . C 6 H 4 N(NH)CH + H + → [C 6 H 4 (NH) 2 CH] +. It can also be deprotonated with stronger bases: . C 6 H 4 N(NH)CH + LiH → Li [C 6 H 4 N 2 CH] + H 2. The imine can be alkylated and also serves as a ligand in coordination chemistry.

In this prototypical example involving benzophenone, the tetrahedral intermediate expels phenyl anion to give benzamide and benzene as the organic products. Benzophenone is a common photosensitizer in photochemistry. It crosses from the S 1 state into the triplet state with nearly 100% yield.
The compound's most noteworthy structural feature is the long carbon-carbon bond of 1.54 Å, which indicates the absence of pi-bonding between the two carbonyl centers.The PhCO centers are planar, but the pair of benzoyl groups are twisted with respect to the other with a dihedral angle of 117°. [5]
Typically the reduction of aldoximes gives both primary amines and secondary amines; however, reaction conditions can be altered (such as the addition of potassium hydroxide in a 1/30 molar ratio) to yield solely primary amines. [12] In general, oximes can be changed to the corresponding amide derivatives by treatment with various acids.
