| Abstract: | 2-(⍺-chloroalkyl)benzimidazoles 1 on reaction with arylsulphinate sodium salt 2, in CH₃CN under PTC conditions, gives 3 which on alkylation yields 1-alky/aralkyl-2-(⍺-aryl sulfonylalkyl) benzimidazoles 4. Alternatively, 4 can also be prepared by the reaction of 2 with 1-alkyl/aralkyl-2- (⍺–chloroalkyl) benzimidazole 5 in CH₃CN using triethylbenzylammonium chloride (TEBAC) as PTC. 5 are obtained from 1 in turn, by alkylation in CH₃CN under PTC conditions. |
