Isoprene reacts with aldehydes in the presence of a catalytic amount of Pd(OAc)2–4PPh3 or Pd(PPh3)4 and a stoichiometric amount of SnCl2 at 40–50 °C in AcOH–H2O to produce 1-substituted 2,2-dimethyl-3-buten-1-ols regioselectively.
Allylic phosphates allylate ketones and aldehydes in the presence of samarium(II) iodide. The coupling proceeds with the preservation of the olefin geometry, however, regio- and stereoselectivity are not high.

Allyl bromides are efficiently coupled with aryl and aliphatic aldehydes in the presence of manganese metal, collidine hydrochloride, bis(diisopropylphosphino)ethane and chromium dichloride. Homoallylic alcohols are isolated in good to excellent yields directly from the reaction mixture.
