organic molecules with various ketones through sp3 C–H bond activation. The thiyl radical generated via single-electron oxidation of TPI by the excited photoredox catalyst abstracted a hydrogen atom from organic molecules such as toluene, benzyl alcohol, alkenes, aldehydes, and THF. The thus-generated carbon-centered radical species underwent addition to ketones and aldehydes. This intrinsically unfavorable
The addition of Grignardreagents to ketones using sub-stoichiometric amounts of LaCl 3 ·2LiCl was studied. Catalytic amounts of LaCl 3 ·2LiCl (30 mol%) provide, in most cases, yields similar to those obtained using a stoichiometric amount.
