摘　　要：二苯并噻吩(DBT)是石油深度脱硫过程中最顽固的成分。随着可持续发展的推广,急需经济绿色的方法实现DBT的脱硫过程。以金属卟啉络合物为催化剂,绿色、廉价的H_(2)O_(2)为氧化剂,发展了光催化的二苯并噻吩的Thia-Baeyer-Villiger氧化重排反应,顺利地将二苯并噻吩以83.6%的收率转化为二苯并亚磺酰内酯(BPS)。所形成的BPS在碱性条件下加热,脱除SO_(2),可以68%的收率形成2-羟基联苯(2-HBP)。该方法成功模拟了生物催化脱硫过程。Dibenzothiophene(DBT)is the most stubborn component in the process of deep desulfurization of oil,and with the promotion of sustainable development,there is an urgent need for an economical and green method to realize the desulfurization process of DBT.A light catalyzed Thia-Baeyer-Villiger oxidative rearrangement reaction of DBT was developed using metalloporphyrin complex as a catalyst and green and inexpensive H_(2)O_(2) as an oxidant.The DBT was smoothly converted to dibenzo[c,e][1,2]oxathiine 6-oxide(BPS)in 83.6% yield.The formed BPS was heated under alkaline conditions to remove SO_(2) to form 2-hydroxybiphenyl(2-HBP)in 68% yield,which successfully simulates the biocatalytic desulfurization process.
