Electric Literature of 106131-61-7,Some common heterocyclic compound, 106131-61-7, name is 3,6-Dichloro-1,2,4,5-tetrazine, molecular formula is C2Cl2N4, 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.
1,2,4-Triazole (3:5 g 50 mmol) was dissolved in 200 mL acetone, and 20 mL (12 mmol) of a 0:6M solution of 3,6-dichloro-tetrazine in acetonitrile was added. The solution was refluxed for 20 h. After cooling the resulting precipitate was washed with water and acetone. 2:1 g (9:9 mmol,83%) of (7) was isolated as an orange powder. – Elemental analysis (C6H4N10, 212.21) exp.
