The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Pentaerythrityltetrabromide(SMILESS: BrCC(CBr)(CBr)CBr,cas:3229-00-3) is researched.Reference of 2,5-Diphenyloxazole. The article 《Synthesis of 2,2-bis(mercaptomethyl)-1,3-propanedithiol》 in relation to this compound, is published in Qingdao Keji Daxue Xuebao, Ziran Kexueban. Let’s take a look at the latest research on this compound (cas:3229-00-3).
2,2-Bis(mercaptomethyl)-1,3-propanedithiol was synthesized using pentaerythritol as raw materials. The synthetic route mainly comprised two steps. In the first step, the intermediate products pentaerythrityl bromide was synthesized from pentaerythritol, and through orthogonal experiment, the yield of pentaerythrityl bromide could reach 78%. In the second step, 2,2-bis(mercaptomethyl)-1,3-propanedithiol was synthesized through replacement and reduction reaction under acidic conditions with a yield of 78%.
