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

متن کاملAn electrochemical tandem reaction: one-pot synthesis of homoallylic alcohols from alcohols in aqueous media.
A tandem electrosynthesis of homoallylic alcohols from alcohols in one-pot was realized. In virtue of this one-pot electrosynthesis, the traditional reaction substrates of allylation were broadened from carbonyl compounds to alcohols.
متن کاملPalladium-catalyzed tandem reaction of 2-hydroxyarylacetonitriles with sodium sulfinates: one-pot synthesis of 2-arylbenzofurans.
The first example of the palladium-catalyzed one-pot synthesis of 2-arylbenzofurans in moderate to excellent yields via a tandem reaction of 2-hydroxyarylacetonitriles with sodium sulfinates is reported. A plausible mechanism for the formation of 2-arylbenzofurans involving desulfinative addition and intramolecular annulation reactions is proposed. Moreover, the present synthetic route to benzo...
متن کاملPTSA-catalyzed Mannich-type-cyclization-oxidation tandem reactions: one-pot synthesis of 1,3,5-substituted pyrazoles from aldehydes, hydrazines and alkynes.
A convenient one-pot Mannich-type-cyclization-oxidation tandem process has been developed for the synthesis of 1,3,5-trisubstituted pyrazoles derivatives from aldehydes, hydrazines and alkynes using p-toluenesulfonic acid monohydrate (PTSA) as a multifunctional catalyst. This method provides a flexible and rapid route to 1,3,5-trisubstituted pyrazoles.
