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.
The first step of the Bouveault aldehyde synthesis is the formation of the Grignard reagent. Upon addition of a N , N -disubstituted formamide (such as dimethylformamide ) a hemiaminal is formed, which can easily be hydrolyzed into the desired aldehyde.
The chemical is a useful reagent for peptide synthesis reactions, where it activates the carboxylic acid partner for subsequent reaction with amines. It is commercially available as 50 % solution in DMF or ethyl acetate as a slightly yellow mixture.
DMCC can also be formed in small amounts (up to 20 ppm) from dimethylformamide (DMF) in the Vilsmeier–Haack reaction [7] or when DMF is used as a catalyst in the reaction of carboxylic acids with thionyl chloride to the corresponding acyl chloride.

Dihydrolevoglucosenone is considered a "green" replacement for DMF. [5] Several standard reactions of organic chemistry, e.g. Menshutkin reaction, [5] Sonogashira coupling, [18] Suzuki-Miyaura coupling [19] and the production of ureas [20] have been carried out in dihydrolevoglucosenone. Formation of ureas using dihydrolevoglucosenone as a solvent
The Vilsmeier reagent is an organic compound with the formula [(CH 3) 2 NCHCl]Cl. It is a salt consisting of the N,N-dimethyliminium cation ([(CH 3 ) 2 N=CHCl] + ) and chloride anion. Depending on the particular reaction, the anion can vary.

N-Methylformamide (NMF) is a colorless, nearly odorless, organic compound and secondary amide with molecular formula CH 3 NHCHO, which is a liquid at room temperature. NMF is mainly used as a reagent in various organic syntheses with limited applications as a highly polar solvent.
