Simple feedstock organic molecules, especially alkenes, are attractive starting materials in organic synthesis because of their wide availability. Direct utilization of such bulk, inert organic molecules for practical and selective chemical reactions, however, remains limited. Herein, we developed a ternary hybrid catalyst system comprising a photoredox catalyst, a hydrogen-atom-transfer catalyst, and a chromium complex catalyst, enabling catalytic allylation of aldehydes with simple alkenes, including feedstock lower alkenes. The reaction proceeded under visible-light irradiation at room temperature and with high functional group tolerance. The reaction was extended to an asymmetric variant by employing a chiral chromium complex catalyst.

Heterogeneous carbonyl allylation by γ-substituted allylic alcohols with Pd-SnCl2 in nonpolar solvent such as diethyl ether was promoted by ultrasound to cause α-addition, with a regioselectivity which is the inverse of that in homogeneous carbonyl allylation in polar solvents such as dimethylformamide, 1,3-dimethylimidazolidin-2-one and tetrahydrofuran-H2O.
