Electric Literature of 28890-99-5, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 28890-99-5, name is 5H-Benzo[d]benzo[4,5]imidazo[1,2-a]imidazole belongs to imidazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
1.00 g (2.44 mmo) 2-iodo-5-pheny-benzimidazoo[t2-a]benzimidazoe, 610mg (2.93 mmo) 6H-benzimidazoo[1 ,2-a]benzimidazoe, 93 mg (0.49 mmo) copper iodide, 1.59 g (4.489 mmo) caesium carbonate and 113 mg (0.98 mmo) L-proine in 10 m DMSO are stirred at 150 C under nitrogen for 43 h. The reaction mixture is poured into water and the product is fi[tered off. The product is washed with water. Coumn chromatography on silicagel with touene/ethy acetate 19/1 ant than 1/1 gives the product (yied: 220 mg (18%)). 1H NMR (400 MHz, THFd8): &59 (d, J= I 8 Hz, I H), 806-81 3 (m, I H), &OO-8O6 (m, 4H), 781787 (m, IH), 775781 (m, 1H), 772774 (m, IH), 75O769 (m, 4H), 743J.49 (m, IH), 731-742 (m, 4H), 724-730 (m, 2H). MS (APC(pos), m/z): 489 (M+1),
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 5H-Benzo[d]benzo[4,5]imidazo[1,2-a]imidazole, other downstream synthetic routes, hurry up and to see.
