We’ll be discussing some of the latest developments in chemical about CAS: 13423-60-4, name is 1-Phenyl-1H-1,2,4-triazole, 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.
EXAMPLE 112 1-phenyl-4-(ethyl)triazoliumbromide 0.220 g (0.0015 mol) 1-phenyltriazole 1 and 1 ml (1.460 g, 0.013 mol) 1-bromopropane 2 are combined in a pressure tube. The reaction mixture is stirred for 2 h at 110 C. Subsequently, it is cooled down to room temperature and the same volume of petroleum ether is added. The precipitated solid is filtered off, washed with petroleum ether, and dried in HV. M 254.13 C10H12N3Br Yield: 0.2307 g (61%) 1H-NMR DM-109 (300 MHz/DMSO): (ppm)=1.58 (t, 3H, 8-H); 4.38 (q, 2H, 7-H); 7.70 (m, 3H, 5/5’/6H); 7.95 (d, 2H, 4/4′-H); 9.53 (s, 1H, 1-H); 11.02 (s, 1H, 2-H) 13C-NMR DM-109 (75.475 MHz/DMSO):
