588-96-5, A common compound: 588-96-5, name is p-Bromophenetole, belongs to ethers-buliding-blocks compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below.
General procedure: The Teflon-lined sealed tube (20 mL) was charged with a 1,4-dioxane solution of sodium fluoroalkoxide RFONa [freshly prepared from fluoroalkanol RFOH (3.3(n + 1) mmol) and Na (3.0 (n + 1) mmol) in 1,4-dioxane (5 mL)], unactivated arylbromide ArBrn (3.0 mmol), CuBr (0.3n mmol) and DMF (3.0n mmol). The sealed tube was heated to 110 C and stirred for 6 h. After the completion of reaction, the concentration of the mixture in vacuo gave a residue, to which was added methyl tert-butyl ether (MTBE, 20 mL) and diluted hydrochloric acid (10 mL, 1.0 mol/L). The organic phase was separated, and the aqueous phase was extracted with MTBE (10 mL 9 3). The combined organic layer was dried over anhydrous MgSO4, andthen concentrated in vacuo to supply a crude product. Lastly, the purification of the crude product provided the desired product via column chromatography on silica gel (eluents: petroleum ether/ethyl acetate 20:1).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, p-Bromophenetole, other downstream synthetic routes, hurry up and to see.
