Chakrabarty, Manas published the artcileA Keggin heteropoly acid as an efficient catalyst for an expeditious, one-pot synthesis of 1-methyl-2-(hetero)arylbenzimidazoles, Application In Synthesis of 2622-67-5, the publication is Tetrahedron Letters (2007), 48(30), 5239-5242, database is CAplus.
The Keggin heteropoly acid, silicotungstic acid, H4SiW12O40, was demonstrated to be highly efficient for an expeditious, one-pot synthesis of arylbenzimidazoles, e.g., I, from N-methyl-1,2-benzenediamine and arylaldehydes in Et acetate at room temperature The catalyst worked equally well for N-phenyl-1,2-benzenediamine.
Tetrahedron Letters published new progress about 2622-67-5. 2622-67-5 belongs to imidazoles-derivatives, auxiliary class Benzimidazole,Benzene,Benzimidazole, name is 1,2-Diphenyl-1H-benzo[d]imidazole, and the molecular formula is C19H14N2, Application In Synthesis of 2622-67-5.
