These common heterocyclic compound, 4054-67-5, name is 3,3′,5,5′-Tetramethyl-1H,1’H-4,4′-bipyrazole, 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. SDS of cas: 4054-67-5
General procedure: A mixture of H2L (0.15 mmol, 0.057 g), phen (0.25 mmol, 0.050 g), Zn(Ac)2·2H2O (0.40 mmol, 0.088 g) and 12 mL H2O was placed in a 25 mL Teflon-lined stainless steel container, heated to 180 C for 72 h,and then cooled to room temperature at a rate of 5 C/h.
The synthetic route of 3,3′,5,5′-Tetramethyl-1H,1’H-4,4′-bipyrazole has been constantly updated, and we look forward to future research findings.
