Application of 4054-67-5,Some common heterocyclic compound, 4054-67-5, name is 3,3′,5,5′-Tetramethyl-1H,1’H-4,4′-bipyrazole, molecular formula is C10H14N4, 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.
The ligands 5-(4-carboxyphenoxy)isophthalicacid (H3L) (0.10 mmol, 0.031 g) and 3,3?,5,5?-tetramethyl-4,4?-bipyrazole(bpz) (0.10 mmol, 0.020 g) as well as Cd(OOCCH3)2·2H2O(0.10 mmol, 0.027 g) were dissolved in 10 mL of H2O and the mixturewas stirred for 30 min and then transferred and sealed in a 25 mLTeflon-lined reactor and heated to 160 C for 72 h, and thereafter cooledto room temperature at a rate of 5 C/h. Yellow block crystals of 1 wereobtained in 62% yield based on cadmium. IR: 3397(v); 2924(m);1615(m); 1557(vs); 1509(m); 1450(s); 1372(vs); 1246(vs); 1108(m);970(m); 779(m); 724(m); 640(m).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3,3′,5,5′-Tetramethyl-1H,1’H-4,4′-bipyrazole, its application will become more common.
