Described are several classes of unusual or unprecedented carbonyl-ene-type reactions, including those between alpha olefins and aromatic aldehydes. Catalyzed by nickel, these processes complement existing Lewis acid-catalyzed methods in several respects.
Ultrasound-promoted Carbonyl Allylation by Allylic Alcohols with Palladium-Tin Dichloride in Nonpolar Solvents: Inversed Regiocontrol of Carbonyl Allylation in Polar Solvents

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.
