Dimethylformamide - Wikipedia
WebDimethylformamide has been found to be a good solvent in the Ullman reaction for the preparation of 2,2′-bipyridine (346) from 2-bromopyridine (Scheme 80) (65CA18018).With two different substrates, a mixture of two homo-coupled dimers and the cross-coupled product is formed, unless there is an optimal difference in reactivity between the two … WebIt is used as a reagent in Bouveault aldehyde synthesis and also in Vilsmeier-Haack reaction. It acts as a catalyst in the synthesis of acyl chlorides. It is used for separating and refining crude from olefin gas. DMF along with methylene chloride acts as a remover of varnish or lacquers.
