The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Spiropentane》. Authors are Murray, M. J.; Stevenson, Eugene H..The article about the compound:Pentaerythrityltetrabromidecas:3229-00-3,SMILESS:BrCC(CBr)(CBr)CBr).Recommanded Product: Pentaerythrityltetrabromide. Through the article, more information about this compound (cas:3229-00-3) is conveyed.
A Raman spectroscopic study of the low-boiling products obtained in the debromination of pentaerythrityl bromide by Zn in aqueous MeOH indicated the presence of a 3rd component (I), which showed lines at 581 and 1033 cm.-1. Reduction in molten AcNH2 containing NaI and Na2CO3 increased the yield of I to 40%. Removal of olefins by AgNO3, AgClO4 and Br gives I, C5H8, b. 38.3-8.5°, n20D 1.4117. I is believed to be CH2.CH2.C.CH2.CH2.
As far as I know, this compound(3229-00-3)Recommanded Product: Pentaerythrityltetrabromide can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
