Barbier-type allylation of aldehydes mediated by antimony(III) chloride–metallic iron or antimony(III) chloride–metallic aluminium
Abstract
Active zero-valent antimony generated from antimony(III) chloride–metallic iron or antimony(III) chloride–metallic aluminium, induced allylation of aldehydes with allylic halides at room temperature to give high yields of the corresponding homoallylic alcohols with high regio- and chemo- selectivity.
