Általános leírás
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.
Alkalmazás
DMF can be used as:
DMF can also be used in the following:
- 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.

Studies on the self-assembly of metal nanoparticles (NPs) in the presence of ions are motivated by the biosensing applications of NP clusters and the capability to control the morphology of clusters of oppositely charged NPs. The effect of ions has

Surface plasmon polaritons can confine electromagnetic fields in subwavelength spaces and are of interest for photonics, optical data storage devices and biosensing applications. In analogy to photons, they exhibit wave-particle duality, whose different aspects have recently been observed in separate

The structural elasticity of metal-organic frameworks (MOFs) is a key property for their functionality. Here, we show that 2D IR spectroscopy with pulse-shaping techniques can probe the ultrafast structural fluctuations of MOFs. 2D IR data, obtained from a vibrational probe
