Aerobic cross-dehydrogenative coupling of toluenes and -phenylenediamines by flavin photocatalysis for the facile synthesis of benzimidazoles
Herein, we demonstrate a green atom-economical synthesis of benzimidazoles via the flavin-photocatalysed aerobic oxidative cross-dehydrogenative coupling of toluenes and o -phenylenediamines. The proposed metal-free reaction proceeds in methanol/H 2 O under visible light irradiation by consuming onl...

| description | Herein, we demonstrate a green atom-economical synthesis of benzimidazoles
via
the flavin-photocatalysed aerobic oxidative cross-dehydrogenative coupling of toluenes and
o
-phenylenediamines. The proposed metal-free reaction proceeds in methanol/H
2
O under visible light irradiation by consuming only molecular oxygen from atmospheric air and produces only water as waste.
An atom-economical synthesis of benzimidazoles was performed by the flavin-photocatalysed aerobic oxidative cross-dehydrogenative coupling of toluenes and
o
-phenylenediamines. |
