A hydroindation of 1,3-dienes by dichloroindium hydride (HInCl2) generates allylic indiums that react with carbonyl or imine moieties in a one-pot treatment. The former reaction proceeds in a radical manner, and the latter is ionic allylation. Moreover, both reactions require no additives such as radical initiators, Lewis acids, or transition metal catalysts.
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.
