DESCRIPTION
General description
N, N-Dimethylformamide (DMF) is an organic compound commonly used as a reagent as well as a solvent in organic synthesis. It plays multiple roles in various reactions such as formylating agent, dehydrating agent, reducing agent as well as a catalyst.
Application DMF can be used as:
A formylating agent for organometallic compounds.
A reactant to prepare Vilsmeier reagent by reacting with phosphorus oxychloride.
A reagent for amination of aryl chlorides in the presence of potassium t-butoxide.
A reducing agent for metal salts to prepare metal colloids.
A catalyst for the regioselective silylation of unprotected carbohydrates.
DMF can also be used in the following:
DMF-Phosgene catalytic system is used to prepare alkyl halides from alcohols.
DMF-POCl3 is used to convert acyclic and cyclic enolizable ketones to β-chloro-α, β-unsaturated aldehydes. DMF-POCl3 is used to synthesize quinoline-3-carbaldehydes from acylanilides.
DMF-SOCl2 combination is used to dehydrate oximes to nitriles.
DMF-Ag2O converts α-bromopropionamides to oxazolidinones.
DMF is frequently used as a solvent in many chemical reactions, which require a high solvency power. Solvent for many hydrophobic organic compounds.
