FeTiO3 has emerged as an interesting semiconductor photocatalyst in organic synthesis. We herein describe a visible-light-induced semiheterogeneous strategy for the synthesis of 3-(2-oxoethyl)indolin-2-ones with moderate to good yields and functional group compatibility using recyclable NHPI redox catalyst.

Direct acylation of heteroarenes with aldehydes has been established through a photoinduced hypervalent iodine-mediated cross-dehydrogenative coupling reaction. The reaction proceeds the in situ generation nucleophilic acyl radicals from via C-H hydrogen atom transfer (HAT), followed by Minisci-type heteroarenes. developed system proved to be suitable for cross-coupling diverse range heterocycles and aldehydes.
