Group 1 salts of carbanions, amides, and hydrides tend to be even stronger bases due to the extreme weakness of their conjugate acids, which are stable hydrocarbons, amines, and dihydrogen. Usually, these bases are created by adding pure alkali metals such as sodium into the conjugate acid.

Results and Discussion In continuation of our interest on the development of green and Acidity of Carboxylic Acids. The pK a 's of some typical carboxylic acids are listed in the following table. When we compare these values with those of comparable alcohols, such as ethanol (pK a = 16) and 2-methyl-2-propanol (pK a = 19), it is clear that carboxylic acids are stronger acids by over ten powers of ten! Amide, any member of either of two classes of nitrogen-containing compounds related to ammonia and amines. The two classes are covalent amides, which are neutral or very weakly acidic substances, and ionic amides, which are strongly alkaline compounds. Alkali metals in the metallic form (e.g.

The few but important reactions of amides are listed here as a summary. However, you can find their mechanisms by following the corresponding links. Hydrolysis of Amides. It is possible to hydrolyze amides with strong acids or bases in harsh reaction conditions:

When writing out the dissociation equation of a strong base, assume that the reverse reaction does not occur, because the conjugate acid of a strong base is very weak. Generally, amides can be hydrolyzed in either acidic or basic solution. The mechanisms are much like those of ester hydrolysis (Section 18-7A), but the reactions are very much slower, a property of great biological importance (which we will discuss later): As we have indicated in Section 23-12, amide hydrolysis can be an important route to amines. Hydrolysis under acidic conditions requires strong acids such as sulfuric or hydrochloric, and temperatures of about \(100^\text{o}\) for several Metal Alkoxides and Amides. Metal Silanoates.

The mechanisms are much like those of ester hydrolysis (Section 18-7A), but the reactions are very much slower, a property of great biological importance (which we will discuss later): Amides are produced in enormous amounts every year, thus, environmentally friendly and selective methods for their formation are of great importance.

On the other hand, amides are much stronger bases than carboxylic acids, esters, aldehydes, and ketones (conjugated acid pKa between -6 and -10). It is estimated in silico that acetamide is represented by resonance structure A for 62% and by B for 28% [4] .

Among the bases examined, K 3PO 4 was the most effective base (entry 3), while Et 3N and K 2CO 3 were less effective (entries 1 and 2) and KF and DBU were ineffective (entries 4 and 5). Using strong base such as, KOtBu resulted in no reaction (entry 6). Due to the acidic character of amide In an acid base equilibrium the equilibrium always favors the weaker acid and base (these are the more stable components). Water is the standard base used for pK a measurements; consequently, anything that stabilizes the conjugate base (A: (–) ) of an acid will necessarily make that acid (H–A) stronger and shift the equilibrium to the right. Amides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of amides with strong reducing agents.
