Abstract

As for gem-difluorinated phenylseleno compounds, indium hydride, in situ generated by transmetallation between InCl3 and NaBH4, was found to be a convenient radical reagent as an alternative to tributyltin hydride. Besides its excellent performance in intramolecular cyclization and radical deselenylation, the NaBH4/InCl3 system also succeeded in intermolecular radical addition between organoselenium compounds and styrene.
