101691-65-0, (Tetrahydro-2H-pyran-4-yl)methyl 4-methylbenzenesulfonate is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Step 2 [0340] (Tetrahydro-2H-pyran-4-yl)methyl 4-methylbenzenesulfonate obtained in Step 1 (1.20 g, 4.44 mmol) was dissolved in acetone (15 mL), sodium iodide (2.00 g, 13.3 mmol) was added thereto, and under reflux with heating, the mixture was stirred for 4 hours. After cooling the reaction mixture to room temperature, the precipitated solid was removed by filtration, and the filtrate was evaporated under reduced pressure. Chloroform was added to the residue, and the precipitated solid was removed by filtration. The filtrate was concentrated under reduced pressure, whereby 4-(iodomethyl)tetrahydro-2H-pyran (0.946 g, 94%) was obtained. 1H NMR (300 MHz, CDCl3, delta): 3.99-3.96 (m, 2H), 3.37 (td, J = 11.7, 2.1 Hz, 2H), 3.10 (d, J = 6.6 Hz, 2H), 1.81-1.65 (m, 3H), 1.37-1.24 (m, 2H)., 101691-65-0
As the paragraph descriping shows that 101691-65-0 is playing an increasingly important role.
