Metal-free sulfenylation of pyrrolo[1,2-a]quinoxaline with diaryl disulfide facilitated by TBATB
A direct metal-free C1–H sulfenylation reaction of pyrrolo[1,2-a]quinoxaline with diaryl disulfides was developed at 50 °C using tetrabutylammonium tribromide (TBATB) as a promoter. Notably, raising the reaction temperature to 100 °C, TBATB played the dual role of both promoter and reactant, resulti...
