Dimethylformamide, DMF is an organic compound with the chemical formula H C O N(CH 3) 2. Its structure is HC(=O)−N( −CH 3 ) 2 . Commonly abbreviated as DMF (although this initialism is sometimes used for dimethylfuran , or dimethyl fumarate ), this colourless liquid is miscible with water and the majority of organic liquids.
An alternative to the weaker base is to use a strong base which is present at a lower concentration than the ketone. For instance, with a slurry of sodium hydride in THF or dimethylformamide (DMF), the base only reacts at the solution–solid interface.
DMF may refer to: Science and technology. Chemistry. Dimethylformamide, a common solvent; Dimethyl fumarate, a small molecule anti-inflammatory human medicine;
DIPEA is a sterically hindered organic base that is commonly employed as a proton scavenger. Thus, like 2,2,6,6-tetramethylpiperidine and triethylamine, DIPEA is a good base but a poor nucleophile, DIPEA has low solubility in water, which makes it very easily recovered in commercial processes, a combination of properties that makes it a useful organic reagent.
Dimethyl fumarate (DMF) is the methyl ester of fumaric acid and is named after the earth smoke plant (Fumaria officinalis). [8] Dimethyl fumarate combined with three other fumaric acid esters (FAEs) is solely licensed in Germany as an oral therapy for psoriasis (brand name Fumaderm ). [ 9 ]

The alkoxide ion is a strong base so the proton is transferred from the carboxylic acid to the alkoxide ion, creating an alcohol: saponification part III. In a classic laboratory procedure, the triglyceride trimyristin is obtained by extracting it from nutmeg with diethyl ether. Saponification to the soap sodium myristate takes place using NaOH ...
Bases, such as pyridine or N,N-dimethylformamide, catalyze acylations. [ 14 ] [ 10 ] These reagents activate the acyl chloride via a nucleophilic catalysis mechanism. The amine attacks the carbonyl bond and presumably [ 23 ] first forms a transient tetrahedral intermediate, then forms a quaternary acylammonium salt by the displacement of ...
