64169-34-2, 5-Bromoisobenzofuran-1(3H)-one is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
5-Bromoisobenzofuran-1(3H)-one (10.00 g, 47.2 mmol),Benzyltriethylammonium chloride (2.20g, 9.4mmol), boron trifluoride diethyl ether (1.20mL, 9.40mmol), xylene (50mL) was added to the reaction flask, and the reaction solution was replaced with nitrogen three times and then heated to 110 C. Reaction for 30 min. Next, thionyl chloride (8.60 mL, 118.0 mmol) was slowly added dropwise to the above reaction solution, and the mixture was heated to 130 C for 6 hours, cooled to 40-50 C, and the reaction was quenched by dropwise addition of methanol (20 mL). The reaction solution is evaporated under reduced pressure to give a solvent.The title compound 1b (11.40 g, 93.0%) was obtained.
64169-34-2, As the paragraph descriping shows that 64169-34-2 is playing an increasingly important role.
