✦ Synopsis

γ-syn-Selective Carbonyl Allylation by 1-Bromo-2-butene with Tin( II) Iodide and Tetrabutylammonium Bromide.

-The first Barbier-type γ-syn-selective carbonyl allylation of aldehydes (II) by (E)-rich bromoalkene (I) in the presence of tin(II) iodide and tetrabutylammonium bromide (or iodide) is presented. A plausible mechanism via an acyclic antiperiplanar transition state is proposed. -(MASUYAMA, Y.; KISHIDA,
