摘要：
Scandium(III) triflate-catalyzed allylation of carbonyl compounds with tetraallylgermane proceeded readily in aqueous nitromethane to afford homoallyl alcohols in excellent to good yields. The presence of H2O is indispensable for the allylation of aldehydes to proceed smoothly. Aldehydes were allylated highly chemoselectively in the presence of ketone moieties.
