Dimethylformamide is an organic compound with the formula (CH3)2NC(O)H. 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. DMF is a common solvent for chemical reactions. Dimethylformamide is odorless, but technical-grade or degraded samples often have a fishy smell. As its name indicates, it is a derivative of formamide, the amide of formic acid. DMF is a polar (hydrophilic) aprotic solvent with a high boiling point. It facilitates reactions that follow polar mechanisms, such as SN2 reactions. DMF is hydrolyzed by strong acids and bases, especially at elevated temperatures. Distillation is therefore conducted under reduced pressure at lower temperatures. In one of its main uses in organic synthesis, DMF was a reagent in the Vilsmeier-Haack reaction, which is used to formylate aromatic compounds.The process involves initial conversion of DMF to a chloroiminium ion, [(CH3)2N=CH(Cl)]+, known as a Vilsmeier reagent, which attacks arenes. Organolithium compounds and Grignard reagents react with DMF to give aldehydes after hydrolysis in a reaction named after Bouveault. Dimethylformamide forms 1:1 adducts with a variety of Lewis acids such as the soft acid I2, and the hard acid phenol. It is classified as a hard Lewis base and its ECW model base parameters are EB= 2.19 and CB= 1.31.[17] Its relative donor strength toward a series of acids, versus other Lewis bases, can be illustrated by C-B plots.

DMF Application

The primary use of DMF is as a solvent with low evaporation rate. DMF is used in the production of acrylic fibers and plastics. It is also used as a solvent in peptide coupling , and in the manufacture of adhesives, synthetic leathers, fibers, films, and surface coatings. As a cheap and common reagent, DMF has many uses in a research laboratory. * DMF is effective at separating and suspending carbon nanotubes, and is recommended by the NIST for use in near infrared spectroscopy of such. * DMF can be utilized as a standard in proton NMR spectroscopy allowing for a quantitative determination of an unknown compound. * In the synthesis of organometallic compounds, it is used as a source of carbon monoxide ligands. * DMF is a common solvent used in electrospinning. * DMF is commonly used in the solvothermal synthesis of Metal-Organic Frameworks. * DMF-d7 in the presence of a catalytic amount of KOt-Bu under microwave heating is a reagent for deuteration of polyaromatic hydrocarbons.
