The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Products of reaction between trimethylamine and pentaerythrityl tetrahalides》. Authors are D’Amico, A.; Verga, G..The article about the compound:Pentaerythrityltetrabromidecas:3229-00-3,SMILESS:BrCC(CBr)(CBr)CBr).Formula: C5H8Br4. Through the article, more information about this compound (cas:3229-00-3) is conveyed.
When 0.02 mole C(CH2Br4) and 0.33 mole Me3N or multiples thereof was heated with cyclohexane in an autoclave 6 hrs. at 190°, among the reaction products only Me4NBr was isolated. An analogous result was obtained with the tetraiodide. Some steric impediment to the formation of C(CH2NHMe.MeI)4 was observed.
Although many compounds look similar to this compound(3229-00-3)Formula: C5H8Br4, numerous studies have shown that this compound(SMILES:BrCC(CBr)(CBr)CBr), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
