this study, in situ catalytically generated allylic indium from 1,3 dienes and InCl2H was developed for use in the allylation of ketones. This protocol resulted in the unprecedented establishment of a successive combining of quaternary C–C bonds, which could then be applied to many types of ketones. Other branched 1,3 dienes and vinyl cyclopropanes, could also be coupled with ketones in a reaction where
Allylic indiums, generated by a conjugate hydroindation of 1,3-dienes by HInCl2, reacted with carbonyl compounds in a one-pot treatment. Both γ- and α-adducts can be obtained depending upon the conditions used.
