Formylation name reaction
WebIn chemistry a formylation reaction is a class of addition reaction, in which a formyl group is added to a substituent to give an aldehyde. Pages in category "Formylation … WebA formylation reaction in organic chemistry refers to organic reactions in which an organic compound is functionalized with a formyl group (-CH=O). The reaction is a route to aldehydes (C-CH=O), formamides (N-CH=O), and formate esters (O-CH=O). A reagent that delivers the formyl group is called a formylating agent.

The direct formylation of aromatic compounds can be accomplished by various methods such as the Gattermann reaction, Gattermann–Koch reaction, Vilsmeier–Haack reaction, or Duff reaction; however, in terms of ease and safety of operations, the Reimer–Tiemann reaction is often the most advantageous route chosen in chemical synthesis. Of the reactions mentioned before, the Reimer–Tiemann reaction is the only route not requiring acidic and/or anhydrous conditions. Additi… WebMar 22, 2024 · The Vilsmeier-Haack reaction or Vilsmeier-Haack formylation uses DMF, phosphoryl chloride (POCl3), and water to convert an electron-rich arene to a substituted benzaldehyde. First, DMF and phosphoryl chloride form an iminium salt called the “Vilsmeier reagent”. Then the aromatic compound attacks the Vilsmeier reagent, disturbing its …
