Application of 67191-35-9, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 67191-35-9, name is 1-Isopropoxy-2-vinylbenzene, This compound has unique chemical properties. The synthetic route is as follows.
A flame-dried Schlenk reaction flask is charged with a stir bar and put under an Ar atmosphere. 923 mg [Dichloro-(3-phenyl-1H-inden-1-ylidene)-bis-(tricyclohexyl-phosphine)-ruthenium(II)] 2a (1.0 mmol; Umicore AG & Co KG, Hanau), 173 mg 2-isopropoxystyrene (1.05 mmol; 1.05 equiv.; Aldrich) and 1026 mg Amberlyst 15-A resin in dry form (4.0 mmol, 4 equiv.; Rohm and Haas Co., Philadelphia, USA) are loaded into the reaction flask and 25 mL dichloromethane (DCM) is added. The reaction is stirred at 40 C. for 75 minutes and the solution colored from red to brown. Subsequently, the reaction mixture is sent through a Pasteur pipette equipped with a cotton plug to remove the Amberlyst resin. Evaporation of all volatiles, suspending the residue in 20 mL n-hexane and subsequent filtration and drying of the precipitate in vacuo afforded 548 mg of the desired compound 3a (yield: 91%)
The chemical industry reduces the impact on the environment during synthesis 1-Isopropoxy-2-vinylbenzene. I believe this compound will play a more active role in future production and life.
