Developed protocol has a very good substrate scope, involves mild reaction conditions and products obtained in good to excellent yields. Method presented the observations in which light alone could affect the remarkable changes with more than 85% energy saving and 75% less reaction time in listed organic transformations.EnglishBenzimidazolesC-N bond formationConcentrated solar radiationPhotocatalysisSolar synthesisConcentrated solar radiation promoted unconventional greener approach: Solvent-free benign synthesis of functionalized benzimidazolesArticle10.24820/ark.5550190.p010.6871551-7012
