Reference of 61326-44-1, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 61326-44-1 name is 1,1,2,2-Tetrakis(4-bromophenyl)ethene, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
In a polar solvent, 1,1,2,2-tetrakis (4-bromophenyl) ethylene, 1,1,2,2-tetrakis (4-bromophenyl)1H-1,2,4-triazole,Potassium carbonate andCopper oxide in the reaction conditions;Wherein 1,1,2,2-tetrakis (4-bromophenyl) ethylene:1H-1,2,4-triazole:Potassium carbonate:The molar ratio of copper oxide is 2: 10-15: 30: 1;The reaction temperature is 80-200 DEG C, the reaction time is 12-120 hoursThe present invention is preferably 1,1,2,2-tetrakis (4-bromophenyl) ethylene:1H-1,2,4-triazole:Potassium carbonate:The molar ratio of copper oxide was2: 10-15: 30: 1;Reaction temperature 100 ,The reaction time was 48 hours.In a polar solvent,Using the “one-pot method”1, 1, 2,(4-bromophenyl) ethene, 1H-1,2,4-triazole, potassium carbonate and copper oxide were heated under heating to produce 1,1,2,2-tetrakis [4-(1H-1,2,4-triazol-1-yl) phenyl] ethylene (L). Yield 60percent.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 1,1,2,2-Tetrakis(4-bromophenyl)ethene, and friends who are interested can also refer to it.
