In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 67191-35-9, name is 1-Isopropoxy-2-vinylbenzene belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Application In Synthesis of 1-Isopropoxy-2-vinylbenzene
A flame-dried Schlenk reaction ask is charged with a stir bar and put under an Ar atmosphere. 748 mg [Dichloro-(3-phenyl-1H-inden-1-yliden)-(1,3-dimesityl-4,5-dihydro-imidazol-2-ylidene)-(pyridine)-ruthenium(II)] 2c (1.00 mmol, Umicore AG & Co KG, Hanau), 173 mg 2-isopropoxystyrene (1.05 mmol; 1.05 equiv) and 1026 mg Amberlyst 15-A resin (4.00 mmol; 4 equiv) is loaded into the reaction ask and 25 mL THF is added. The reaction mixture is stirred at 40 C. for 1 hour, during which the reaction mixture turns from red to green color. 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 n-hexane and subsequent filtration and drying in vacuo afforded 578 mg of the desired compound 3b as a green, air-stable product (yield: 94%). 1H and 13C NMR analytics 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.
