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 ]
Benzaldehyde oxime undergoes Beckmann rearrangement to form benzamide, catalyzed by nickel salts [3] or photocatalyzed by BODIPY. [4] Its dehydration yields benzonitrile . It can be hydrolyzed to regenerate benzaldehyde.

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 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.
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.
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.
N,N′-Dicyclohexylcarbodiimide (DCC or DCCD) [1] is an organic compound with the chemical formula (C 6 H 11 N) 2 C. It is a waxy white solid with a sweet odor. Its primary use is to couple amino acids during artificial peptide synthesis.
