Acetamide (systematic name: ethanamide) is an organic compound with the formula CH 3 CONH 2. It is an amide derived from ammonia and acetic acid . It finds some use as a plasticizer and as an industrial solvent. [ 5 ]
Structure of acetamide hydrogen-bonded dimer from X-ray crystallography. Selected distances: C-O: 1.243, C-N, 1.325, N---O, 2.925 Å. Color code: red = O, blue = N, gray = C, white = H. [8] The lone pair of electrons on the nitrogen atom is delocalized into the Carbonyl group, thus forming a partial double bond between nitrogen and carbon.
The chemical reactions of dimethylacetamide are typical of N,N-disubstituted amides. Hydrolysis of the acyl-N bond occurs in the presence of acids: . CH 3 CON(CH 3) 2 + H 2 O + HCl → CH 3 COOH + (CH 3) 2 NH 2 + Cl −
For example, acetic acid forms a dimer in the gas phase, where the monomer units are held together by hydrogen bonds. [3] Many OH-containing molecules form dimers, e.g. the water dimer . Dimers that form based on weak electrostatic interaction and/or van der Waals interactions have a short lifetime, but can be stabilized through special ...

A common route to primary amidines is the Pinner reaction.Reaction of the nitrile with alcohol in the presence of acid gives an iminoether.Treatment of the resulting compound with ammonia then completes the conversion to the amidine. [1]
As a source of amidine, acetamidine hydrochloride is a precursor to the industrial and laboratory synthesis of many nitrogen compounds.It reacts with β-dicarbonyls to produce substituted pyrimidines, [5] with acetaldehydes to form substituted imidazoles, [6] and with imidates to form substituted triazines.
