The use of aqueous neutral media leads to excellent yields of homoallylic alcohols from reaction sof allyl halides with carbonyl compounds in the presence of tin or zinc. The stereochemicalcourse and range of application of this reaction have been investigated.

Indium-Mediated Allylation of the <i>N</i>,<i>N</i>-Dimethyl Glyoxal Mono-Hydrazone: One-Pot Synthesis of Bis-Homoallyl, and of Homoallyl-Alkyl 1,2-Diols
Hydrazones behave as highly reactive species in the allylation under Barbier conditions. Nucleophilic addition of an alkyllithium to the carbonyl moiety of the glyoxal mono-hydrazone followed by indium-mediated allylation, leads in high yields to bis-functionalized 1,2-diols in a one-pot two-step reaction.
