Metal-free oxidative radical addition of carbonyl compounds to α,α-diaryl allylic alcohols: synthesis of highly functionalized ketones.
TL;DR: A metal-free direct alkylation of simple carbonyl compounds (ketones, esters, and amides) with α,α-diaryl allylic alcohols is described, providing facile access to highly functionalized dicarbonyl ketones by a radical addition/1,2-aryl migration cascade.

Metal‐Free Desulfonylation Reaction Through Visible‐Light Photoredox Catalysis
TL;DR: The desulfonylation of -arylketosulfones has been achieved in good to excellent yields by using 3-W blue LEDs light, 1 mol-% organic dye eosin Y bis(tetrabutylammonium salt) as photocatalyst, and diisopropylethylamine as reducing agent as discussed by the authors.
