Dubey, P. K. published the artcileA facile solvent-free synthesis of 1-alkyl/aralkyl-2-(1-arylsulfonylalkyl) benzimidazoles using “TBAB” as surface catalyst, Safety of 2-(Chloromethyl)-1-methyl-1H-benzo[d]imidazole, the publication is Journal of Heterocyclic Chemistry (2010), 47(6), 1317-1322, database is CAplus.
Reaction of 2-(α-chloroalkyl)benzimidazoles with Na arylsulfinates (I) under solvent-free conditions in the presence of Bu4NBr as surface catalyst, by simple phys. grinding using mortar and pestle, gave 2(1H)-[α-(arylsulfonyl)alkyl]benzimidazoles. Subsequent treatment with alkylating agents under solvent-free conditions resulted in 1-alkyl/aralkyl-2-[α-(arylsulfonyl)alkyl]benzimidazoles. Alternatively, the latter were also prepared directly from 1-alkyl/aralkyl-2-(α-chloroalkyl)benzimidazoles by reaction with I. All the reactions were free from organic solvents.
Journal of Heterocyclic Chemistry published new progress about 4760-35-4. 4760-35-4 belongs to imidazoles-derivatives, auxiliary class Chloride,Benzimidazole, name is 2-(Chloromethyl)-1-methyl-1H-benzo[d]imidazole, and the molecular formula is C9H9ClN2, Safety of 2-(Chloromethyl)-1-methyl-1H-benzo[d]imidazole.
