5381-20-4, Thianaphthene-3-carboxaldehyde is a benzothiophene compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: Benzo[b]thiophene-3-carbaldehyde (40 mg, 0.25 mmol, 1.0 equiv),Pd(TFA) 2 (4.2 mg, 5 mol%), (4-FC 6 H 4 ) 3 P (9.5 mg, 12 mol%), DPEphos (8mg, 6 mol%), and Cs 2 CO 3 (122 mg, 0.375 mmol) were placed in atransparent Schlenk tube equipped with a stirring bar. The tube wasevacuated and filled with argon for three times. Degassed DMF (2.5mL) and tert-butyl bromide (51 mg, 0.375 mmol, 1.5 equiv) were add-ed via a gastight syringe. The reaction mixture was stirred under theirradiation of 36 W blue LEDs (distance app. 2.0-3.0 cm from thebulb) at r.t. for 24 h. The mixture was quenched with brine and ex-tracted with EtOAc (3 ¡Á 10 mL). The organic layers were combinedand concentrated under reduced pressure. The product was purifiedby flash column chromatography on silica gel using PE or a mixture of PEand EtOAc (10:1 v/v) as eluent; yield: 50.1 mg (92%); pale yellow liquid.
As the paragraph descriping shows that 5381-20-4 is playing an increasingly important role.
