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.
250ml four bottles,In the atmosphere of nitrogen gas,0.01 mol of 5H-benzimidazol [1,2-a] benzimidazole was added,0.015 mol of 13- (4-bromophenyl) -10,10-dimethyl-10,13-dihydrobenzofuran [2,3-c] indole [1,2-g] carbazole,0.03 mol of sodium tert-butoxide,1 x 10-4 mol Pd2 (dba) 3,1 x 10-4 mol tri-tert-butylphosphine,150 ml of toluene,Heated to reflux for 24 hours,Sampling point plate, the reaction is complete, natural cooling, filtration, the filtrate steamed, silica gel column, the target product, purity 99.25, yield 49.00%.
The synthetic route of 5H-Benzo[d]benzo[4,5]imidazo[1,2-a]imidazole has been constantly updated, and we look forward to future research findings.
