In summary, we have developed a photocatalytic way to α-
naphthols from 1-tetralons under ambient conditions. By
virtue of the single electron transfer oxidation process, keto-
enol radical cation becomes available for the dehydrogenation
of 1-tetralones to α-naphthols in one pot reaction without any
sacrificial oxidants under mild conditions, and an equivalent
amount of H2 is generated as the sole byproduct. More
importantly, the continuous-flow approach enables the
transformation of a diverse array of 1-tetralones to α-
naphthols in high yield and efficiency with shorter reaction
time. Further investigation to broaden the synthetic
application, explore the more suitable photocatalysts to
accelerate single electron transfer process and the keto-enol
tautomerization-driven radial cation formation are actively
pursued in our laboratory, and the results will be reported in
due course.
