95-15-8,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.
To a 13¡Á100 mm borosilicate glass heavy wall test tube was added benzothiophene (73.8 mg, 0.55 mmol). A stock solution of Pd(OAc)2 (16.8 mg, 0.075 mmol, 75 mM) and BQ (8.1 mg, 0.075 mmol, 75 mM) in 1.0 mL DMSO was created. A stock solution of Cu(OAc)2.H2O (57.1 mg, 0.286 mmol, 143 mM) and phd (60.1 mg, 0.286 mmol, 143 mM) in 2.0 mL DMSO was created. Then, 100 muL DMSO, followed by 220 muL (0.0165 mmol) of the Pd(OAc)2/BQ stock solution, and 115 muL (0.0164 mmol) of the Cu(OAc)2.H2O/phd stock solution were added to the test tube. The test tube with reaction mixture was placed on an orbital mixing block with heating element. The mixing block was sealed, purged with O2 for five minutes, cooling water was turned on, and then the block was heated to 120 C. under 1 atm O2 with shaking for 48 hours. After 48 hours, the shaking was stopped, the block was depressurized, and the reaction test tube was removed and allowed to cool. An aliquot of a stock solution of 1,3,5-trimethoxybenzene in THF was added to the reaction mixture, and the DMSO/THF mixture was filtered through the Celite, and then the Celite was washed once more with THF. The filtrate was diluted with additional THF, and then it was shaken so that everything was evenly mixed.
As the paragraph descriping shows that 95-15-8 is playing an increasingly important role.
