SiCl4 can be conveniently activated by catalytic amounts of dimethylsulfoxide or other readily-available sulfoxides for the allylation of aromatic, hetero-aromatic and unsaturated aldehydes in the presence of allyltributyl stannane. Chiral aryl methyl sulfoxides have been used to develop asymmetric allylation methods, as well as probe the aldehyde substrate scope.

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
