Reference of 13423-60-4, The chemical industry reduces the impact on the environment during synthesis 13423-60-4, name is 1-Phenyl-1H-1,2,4-triazole, I believe this compound will play a more active role in future production and life.
EXAMPLE 110 1-phenyl-4-(hex-1-yl)triazolium bromide 0.300 g (0.002 mol) 1-phenyltriazole 1 and 0.842 ml (0.990 g, 0.006 mol) 1-bromohexane 2 were dissolved in a pressure tube in 5 ml THF. The reaction mixture was stirred 3 d at 110 C. On account of a broken seal the solvent had evaporated was after that time. 1-bromohexane 2 and THF were added again and stirring was continued. The reaction mixture was cooled down and the same volume petroleum ether added. The precipitated solid is filtered off, washed with petroleum ether, and dried in HV. While the solvent had already evaporated the reaction seemed to run better, because this experiment provided considerably higher yields than all THF experiments. M 310.24 C14H20N3Br Yield: 0.4601 g (74%) 1H-NMR DM-107 (300 MHz/DMSO): delta (ppm)=0.88 (t, 3H, 12-H); 1.33 (m, 6H, 9/10/11H); 1.94 (q, 2H, 8-H); 4.31 (t, 2H, 7-H); 7.70 (m, 3H, 5/5’/6H); 7.96 (d, 2H, 4/4′-H); 9.51 (s, 1H, 1-H); 11.00 (s, 1H, 2-H) 13C-NMR DM-107.w (300 MHz/DMSO):
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-Phenyl-1H-1,2,4-triazole, other downstream synthetic routes, hurry up and to see.
