description

Dual proton and carbon-13 NMR spectra of dimethylchloroformiminium chloride 1 and dimethylformamide hydrochloride 2 in CDCl3 at different temperatures have been measured and the results compared to proton NMR data of dimethyl formamide 3. The energy barriers of internal rotation about C-N bond in 1 and 2 were considerably lower than that of 3. The values of E were 39.3 for 1, 55.9 for 2 and (lit. value) 89.3 for 3 (in kJ/mole).
