Witryna17 mar 2015 · We present a combined computational and threshold photoelectron photoion coincidence study of two isotopologues of dimethyl ether, (DME − h 6) n and (DME − d 6) n n = 1 and 2, in the 9–14 eV photon energy range. Multiple isomers of neutral dimethyl ether dimer were considered, all of which may be present, and … WitrynaIn dimethyl ether (CH 3−O−CH 3) there are no H -atoms attached directly to O and hence no H -bonding is possible in ethers. Even if ether is mixed with polar solvents like H 2O or H 2O 2 the H -bond formed with O -atom of ether is very very weak due to stearic repulsion of R -groups in ethers. Witryna3-Aminomethylation of salicylalkylamides afforded hybrids with a Mannich base. In addition, it triggered the rotation of the amide bond. The observed conformational switch is driven by strong intramolecular hydrogen bonding between the Mannich base and phenolic group.
