Copper‐impregnated magnesium‐lanthanum mixed oxide [Cu(II)/Mg−La] was used as catalyst in synthesis of homoallylic alcohols from aldehydes and ketones using allyltributylstannane as the allylating source. The present protocol provides a great application potential for the synthesis of corresponding allyl alcohols with excellent yields and selectivity. The catalyst exhibits broad functional group compatibility with a variety of substituted aldehydes and ketones to furnish the desired products in high yields under heterogeneous conditions. Importantly, the heterogeneous catalyst could be recovered from the reaction mixture by centrifugation and used up to three cycles.
