Electric Literature of 103755-58-4, New discoveries in chemical research and development in 2021. We’ll be discussing some of the latest developments in chemical about CAS: 103755-58-4, name is (1-Phenyl-1H-1,2,3-triazol-4-yl)methanol, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Phosphorus(III) bromide, 9.7 mL (0.05 mol), was added with vigorous stirring to a solution of 8.75 g (0.05 mol) of (1-phenyl-1H-1,2,3-triazol-4-yl)metha-nol (11) in 200 mL of anhydrous benzene. The mixture was heated for 2 h and cooled, 50 g of crushed ice was added, and the mixture was neutralized with a saturat-ed solution of sodium carbonate. The organic layer was separated and washed with a saturated solution of sodium carbonate, and the solvent was evaporated under reduced pressure. Yield 10.0 g (84%), mp 124-126C. 1 H NMR spectrum (500 MHz, DMSO-d 6 ), delta, ppm: 4.84 s (2H, CH 2 ), 7.52 t (1H, p-H, J = 7.2 Hz), 7.62 t (2H, m-H, J = 7.2 Hz), 8.92 s (1H, 5-H), 7.91 d (2H o-H, J = 7.2 Hz). Mass spectrum, m/z (I rel , %): 238 (100), 240 (97) [M + H] + . Found, %: C 45.23; H 3.30; N 17.62. C 9 H 8 BrN 3 . Calculated, %: C 45.40; H 3.39; N 17.65.
Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about (1-Phenyl-1H-1,2,3-triazol-4-yl)methanol.
