Adding a certain compound to certain chemical reactions, such as: 91-16-7, name is 1,2-Dimethoxybenzene, belongs to ethers-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 91-16-7, category: ethers-buliding-blocks
A solution of 1,2-dimethoxybenzene (10 g, 72.4 mmol) in dichloromethane(50 ml) was added dropwise to a suspension of anhydrous FeCl3 (35.22 g, 217.2 mmol) in dichloromethane (100 ml) and concentrated sulphuric acid (0.5 ml). After complete addition (15 min), the reaction mixture was further stirred for 3 h at room temperature. 200 ml of methanol were then slowly added under vigorous stirring. The obtained mixture was further stirred for additional 30 min. And the precipitate was filtered off, washed with methanol (5 × 100 ml) and dried under reduced pressure to give a purple solid. Yield: 80%, 1HNMR (CDCl3) delta/ppm: 4.10 (s, 18H, OCH3), 7.80 (s, 6H, ArH).
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, 1,2-Dimethoxybenzene, other downstream synthetic routes, hurry up and to see.
