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] The related compound N,N-dimethylacetamide (DMA) is more widely used, but it is not
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.
In the usual implementation, hydrogen peroxide is used together with acetamide. This mixture does not react with ammonia directly but does so in the presence of methyl ethyl ketone to give the oxaziridine. Balanced equations for the individual steps are as follows. Imine formation through condensation: Me(Et)C=O + NH 3 → Me(Et)C=NH + H 2 O
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 −
Hydrogenation of acetonitrile, acetamide, and nitroethane affords ethylamine. These reactions can be effected stoichiometrically using lithium aluminium hydride . In another route, ethylamine can be synthesized via nucleophilic substitution of a haloethane (such as chloroethane or bromoethane ) with ammonia , utilizing a strong base such as ...
Aldol structural units are found in many important molecules, whether naturally occurring or synthetic. [8] [9] The reaction is well used on an industrial scale, notably of pentaerythritol, [10] trimethylolpropane, the plasticizer precursor 2-ethylhexanol, and the drug Lipitor (atorvastatin, calcium salt).
