Various allylic compounds can be effectively applied to palladium-catalyzed allylation of carbonylcompounds via the formation of π-allylpalladium(II) intermediates and their transmetalation with indium in the presence ofindium trichloride in aqueousmedia.
各种烯丙基化合物可以有效地应用于钯催化的羰基化合物的烯丙基化反应,通过在水介质中三氯化铟存在下形成 π-烯丙基钯 (II) 中间体及其与铟的金属转移反应。

The reaction of 1,3-dibromopropene with carbonyl compounds mediated by indium in water gave bis-allylation products connected to the same carbon. Such a reactivity effectively constitutes a gem-allyldianionsynthon.
Ytterbium triflate catalysed allylation of aldehydes: An unusual benzoic acid induced acceleration

Addition of one equivalent of benzoic acid greatly enhances the efficiency of our ytterbium triflate catalyzed allylation of aldehydes with allyltributyltin in acetonitrile. Crucial modifications to reaction conditions result in a dramatically increased rate at remarkably low catalyst loading. (C) 1998 Elsevier Science Ltd. All rights reserved.
