摘要:

以苯硫酚和碳酸乙烯酯为原料,1,5⁃二氮杂二环[4.3.0]⁃5⁃烯(DBN)为催化剂,合成了2⁃苯硫基乙醇。研究了催化剂种类及其物质的量、反应时间、反应温度等条件对反应的影响。结果表明,在DBN为催化剂、n(苯硫酚)/nDBN=100、反应时间为10 min、反应温度为50 ℃时,2⁃苯硫基乙醇的转化率达到90%以上;当反应温度为90 ℃时,可获得100%的转化率,该合成路线催化剂的选择性均为100%。根据软硬酸碱理论对反应机理进行了探讨。

Abstract: 2⁃Phenylthioethanol was synthesized from thiophenol and ethylene carbonate using 1,5⁃diazabicyclo[4.3.0]non⁃5⁃ene (DBN) as a catalyst. The effects of catalyst type and amount, reaction time and temperature on the reaction were studied. The results showed that, the conversion of 2⁃phenylthioethanol can reach more than 90% when the reaction temperature is 50 ℃ and 100% conversion can be obtained when the reaction temperature is 90 ℃ using DBN as the catalyst, n(thiophenol)/n(DBN)=100, the reaction time 10 min. The selectivity of the catalyst of the synthetic route is 100% The paper discusses the reaction mechanism according to the theory of soft and hard acid and alkali.

Key words: 2?Phenylthioethanol, Thiophenol, Ethylene carbonate, DBN
