## Mecanismo de ação

### 1. Protonation and Deprotonation

NMF acts as a strong base in organic reactions, facilitating the deprotonation of weakly acidic substrates. This property is particularly useful in the synthesis of amides, esters, and other nitrogen-containing compounds. The following table illustrates the protonation and deprotonation reactions involving NMF:

| Reaction | Product |
| --- | --- |
| NMF + H2O → NMF·H+ + OH- | NMF·H+ (protonated NMF) |
| NMF·H+ + R-NH2 → NMF + R-NH3+ | R-NH3+ (amine) |

### 2. Activation of Electrophiles

NMF can also activate electrophiles, such as alkyl halides and sulfonyl chlorides, by deprotonating them. This activation allows for more efficient nucleophilic substitution reactions. The following table demonstrates the activation of an alkyl halide by NMF:

| Reaction | Product |
| --- | --- |
| NMF + R-Cl → NMF·Cl- + H+ | NMF·Cl- (activated electrophile) |
| NMF·Cl- + Nu- → R-Nu + NMF | R-Nu (alkyl halide substitution product) |

### 3. Solubility Enhancement

The trifluoromethyl groups in NMF increase the solubility of the reagent in organic solvents, which is crucial for efficient reaction kinetics. This property allows for the use of NMF in a wide range of organic transformations.

## Scope of Applications

| R-NHCOCl + NMF → R-CONH2 + NMF·Cl- | R-CONH2 (amide) |

### 2. Ester Synthesis

NMF can also be used in the synthesis of esters, which are important in the production of flavors, fragrances, and pharmaceuticals. The following table illustrates the use of NMF in ester synthesis:

| Reaction | Product |
| --- | --- |
| R-OH + R'-COCl → R-O-CO-R' + HCl | R-O-CO-R' (ester) |
| R-O-CO-R' + NMF → R-O-CO-R' + NMF·Cl- | R-O-CO-R' (ester) |
