Adding a certain compound to certain chemical reactions, such as: 28890-99-5, name is 5H-Benzo[d]benzo[4,5]imidazo[1,2-a]imidazole, belongs to imidazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 28890-99-5, Application In Synthesis of 5H-Benzo[d]benzo[4,5]imidazo[1,2-a]imidazole
36.0 g (174 mmol) 6H-benzimidazolo[1 ,2-a]benzimidazole, 77.8 (174 mmol) 3-iodo-9-(p- tolylsulfonyl) carbazole, 106 g (0.500 mol) potassium phosphate, 5.5 g (28.9 mmol) copper iodide, and 11 1 g (0.972 mol) trans-cyclohexane-1.2-diamimne in 900 ml dioxane are stir- red at 100 C for 48 h under nitrogen. The product is filtered off, washed with dioxane and ethanol and is used without purification for the next reaction step.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 5H-Benzo[d]benzo[4,5]imidazo[1,2-a]imidazole, and friends who are interested can also refer to it.
