Use of NMR spectrometry for studying the acetolysis of hexamethylenetetramine III. The reaction between hexamethylenetetramine and acetic anhydride to form TRAT
View through CrossRef
AbstractThe acetolysis of hexamethylenetetramine (HA) to form 1,3,5‐triacetyl‐1,3,5‐triazacyclohexane (TRAT) has studied by NMR. It was found that this reaction experienced two different courses. HA turned to TRAT through the intermediate 3,7‐diacetyl‐1,3,5,7‐tetraaza‐[3.3.1]‐bicyclononace (DAPT), and HA converted at first to an intermediate M1, which gave TRAT through another intermediate M2 in the presence of water. Based on the 1H and 13C spectra, the change in the spectra with reaction and the possibility of reaction, we assumed both the structure of M2 and its reaction mechanism.
