With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.95-15-8,Thianaphthene,as a common compound, the synthetic route is as follows.
95-15-8, General procedure: Benzo[b]thiophene was used as an arene, and 1,1,2,2-tetrabromoethane (Br2HCCHBr2) was used as an electrophilic reagent. The arene was reacted with Na-TMP in the same manner as in Experiment Number 2, the electrophilic reagent was added thereto and reacted therewith at -78 C. for 1 hour, the product was then evaluated, and the yield of isolated 2-bromo-benzo[b]thiophene in which a bromo group (-Br) was added at 2-position of benzo[b]thiophene was calculated. The isolated yield was 81%.
As the paragraph descriping shows that 95-15-8 is playing an increasingly important role.
