Tertiaryamines can be used in place of aldehydes and carboxylic derivatives as partners in the synthesis of benzimidazoles. Dehydrogenative amine activation under heterogeneous catalysis was developed for the direct transformation of tertiaryamines into benzimidazoles. Good yields and efficient recovery and recycling of the catalyst are some of the advantages of this new methodology, which shows
