1768-64-5, 4-Chlorotetrahydropyran is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Example 8 Preparation of ethyl 1-(4-tetrahydropyranyl)eth-1-ene-2 -carboxylate 9.6 g (400 mmol) of magnesium turnings are covered with tetrahydrofuran, about 2 ml of bromomethane are added, and the mixture is warmed to reflux. 38.45 g (300 mmol) of 4-chlorotetrahydropyran, dissolved in 100 ml of tetrahydrofuran, are added dropwise. The mixture is subsequently stirred for a further 30 minutes and cooled to 10 C., 42.9 g (300 mmol) of ethyl 1-(dimethylamino)eth-1-ene-2-carboxylate are added dropwise, and the mixture is stirred for a further 12 hours. Customary work-up gives 31.4 g (60%) of ethyl 1-(4-tetrahydropyranyl)eth-1-ene-2-carboxylate of boiling point 120 to 140 C./10 mmHg.
1768-64-5, As the paragraph descriping shows that 1768-64-5 is playing an increasingly important role.
