Abstract
- This work reports the first visible-light mediated cobalt-catalyzed aldehyde allylation with simple alkenes to produce homo-allylic alcohols. This novel strategy directly uses easily available unactivated alkenes as alternative allyl sources instead of pre-synthesized allylic halides/alcohols, thus bypassing the need for exogeneous reductants. Mechanistic studies suggest that the unprecedented combination of allyl radical intermediates and CoI species to generate nucleophilic π-allylcobaltII under photoredox conditions represents the key step in the catalytic cycle.
