substituent 1g in our procedure. In contrast, with other
photocatalysts, where the presence of a base is required, the
deprotonation of substrate 1g takes place first and the reaction
does not proceed. In addition, the semiquinone redox state
[RFTA-H]• has been previously described as intermediate
based on spectroscopic experiments.17 Deprotonation of the
thiobenzanilide radical cation 1a•+ gives the sulfur radical that
after cyclization and further rearomatization by any oxidant
species affords 2-phenylbenzothiazole. Peroxydisulfate is
necessary to close the catalytic cycle and return RFTA to its
ground state.
In conclusion, an efficient photochemical approach for
visible-light-driven C−H functionalization/C−S bond forma-
tion has been developed. This methodology provides access to
2-substituted benzothiazoles avoiding harsh reaction condi-
tions. Moreover, the use of riboflavin as photocatalyst shows
important advances over transition-metal catalysis and other
organic photocatalysts and does not require the use of strong
bases. Riboflavin is an inexpensive natural reagent that allows
benzothiazole synthesis compatible with a wide range of
functional groups. This environmentally friendly procedure
could be advantageous for pharmaceutical uses.
