Iodine is dissolved in diethyl ether
WebIn this example diethyl ether is split into ethanol and iodoethane: The reaction is regioselective , as iodide tends to attack the less sterically hindered ether carbon. If an excess of HI is used, the alcohol formed in this reaction will be converted to a 2nd equivalent of alkyl iodide, as in the conversion of primary alcohols into alkyl iodides. WebIodine complexes in inert solvents—IV. : The reaction between diethyl ether and iodine in the pure solvent or in inert solvents. P.A.D. de Maine. Add to Mendeley. …

WebBecause diethyl ether has a dipole moment, polar substances readily dissolve in it. Polar compounds that can serve as hydrogen bond donors dissolve in diethyl ether because they can form hydrogen bonds to the nonbonding electron pairs of the ether oxygen atoms. Ethers are aprotic.
Webhello, I dont understand the purpose of Iodine in a grignard reaction with bromobenzene, and magnesium in diethyl ether! I think I read somewhere that the iodine improves the reactivity of this reaction? :/ I am not sure how this reaction mechanism would look like..
