Study on the Regioselectivity of Chlorination of 3,5- Di-t -butyltoluene
摘要/Abstract
摘要:
对3,5二叔丁基甲苯(3,5DBT)二氯代反应的区域选择性进行了研究。结果表明,3,5二叔丁基甲苯中的2个叔丁基虽然对甲基的对位有较好的封闭作用,但是,在对位仍能发生氯代反应。其影响因素较为复杂,硫醚能显着影响二叔丁基甲苯氯代反应的区域选择性。
Abstract:
The selectivity of dichlorination of 3,5-dit buty ltoluene(3,5-DBT) was studied.The result shows that two butyls in 3,5-DBT can not protect the 4-position perfectly, and there is always 2,4-dichloro isomer to be formed in dichlorination, the factors of influencing selectivity are complex, sulfide is especially ef fective on regioselective dichlorination of 3,5-DBT.
