Seal the resealable reaction tube containing the magnetic follower with a rubber septum. Dry the tube with a flame under an argon atmosphere. Add tBu3P·HBF4 (10.9 mg, 0.0377 mmol) and Pd2(dba)3 (17.3 mg, 0.0189 mmol) to the tube. Dissolve aryl bromide (83.6 mg) in anhydrous toluene (0.9 mL). Add the resulting solution to the tube using a syringe. Add tert-butyl acetate (87.6 mg) to the tube. Cool the reaction mixture to -78°C. Degas the reaction mixture with argon for 15 min. Add degassed LiHDMS solution (0.942 mL, 1 M toluene solution) to the mixture using a syringe. Degause the reaction mixture for 15 minutes. Replace the rubber diaphragm with a screw cap. Stir the reaction mixture at room temperature for 16 hours. Quench the reaction by adding saturated NaHCO3 aqueous solution (25 mL). Extract the aqueous layer with Et2O (3 × 25 mL). Dry the combined organic matter with Na2SO4. Filter the combined organic matter. Remove the solvent under vacuum. Purify the product by rapid column chromatography [petroleum/EtOAc 50:1, fractionated to 5:1]. |

3-?Hydroxyisoquinoline is a compound used in a polymeric mixture of polyvinyl alcohol (PVA) along with Nile Red to produce white light through Fo?rster resonance energy transfer. | [General Description]
Two excited state proton transfer mechanisms of 3-hydroxyisoquinoline (3HIQ) in cyclohexane and acetic acid has been investigated by time-dependent density functional theory (TDDFT). Spectral and photo physical properties of 3-HIQ in various protic/aprotic solvents were studied. Phototautomerization of 3-HIQ has been reported. Oxo-hydroxy tautomerism and phototautomerism of 3-HIQ has been studied using the matrix-isolation technique. |
