Both aldimines and ketimines are allylated under simple Barbier-type conditions using allylbromide and commercial magnesium foil or zinc dust in tetrahydrofuran at room temperature.
Reductive addition of allyl bromide to imines has been performed with a combination of a catalytic amount of PbBr2 (0.03–0.1 equiv.) and Al (1 equiv.) in Et2O containing BF3·OEt2 (1.1 equiv).
Barbier-type allylation of unactivated aldimines with allyl bromides in the presence of indium powder took place rapidly in alcoholic solvents to give homoallylic amines in fair to good yields.

Cuprous iodide is a very effective catalyst for the three-component condensation of an aldehyde, benzylamine and allyltributylstannane in DMF to produce homoallylicamines in high yields.
