Synthetic Route of 67191-35-9, A common heterocyclic compound, 67191-35-9, name is 1-Isopropoxy-2-vinylbenzene, molecular formula is C11H14O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
A flame-dried Schlenk reaction flask is charged with a stir bar and put under an Ar atmosphere. 849 mg 1b (1.00 mmol), 173 mg 2-isopropoxystyrene (1.05 mmol; 1.05 equiv) and 1026 mg Amberlyst 15-A resin in dry form (4.00 mmol; 4 equiv) was loaded into the reaction flask and 25 mL THF is added. The reaction was stirred at 40 C. for 1.5 hour, during which the reaction mixture colors from pink to green. Then, the reaction mixture is sent through a Pasteur pipette equipped with a cotton plug to remove the polystyrene sulfonic acid resin. Evaporation of all volatiles, suspending in 20 mL hexane and subsequent filtration and drying in vacuo afforded the desired compound 3b as a green air-stable product. 1H and 13C NMR analyses are in agreement with those found in literature.
The synthetic route of 67191-35-9 has been constantly updated, and we look forward to future research findings.
