abstract

the catalytic air oxidation-trimerization of alcohols was carried out with hetropolyacids. in the presence of hetropolyacid formation of cyclotrimers of alcohols and aldol condensation products was observed. the 1,3,5-trioxanes were major and aldol condensation compounds were minor products.

Urea-hydrogen peroxide/silica phosphoric acid-catalyzed oxidation- condensation Tandem reaction: One-pot synthesis of 2-substituted benzimidazoles from alcohols

An efficient one-pot oxidation/condensation tandem process has been developed for the synthesis of 2-substituted benzimidazole derivatives from benzylic alcohols and 1,2-phenylenediamine with use of urea-hydrogen peroxide/silica phosphoric acid as a bifunctional catalyst. This method provides a rapid and efficient access to 2-substituted benzimidazoles.
