Abstract
A reagent combination of β-SnO and catalytic Cu2O promotes the reaction of allyl halides with aldehyde, cyclic monoketone, 1,2-diketone, 1,3-diketone, and anhydride in DCM-H2O, leading to corresponding homoallylic alcohols having exclusive γ-regioselectivity. Surface probing by XRD and XPS indicates that the reagent activates allyl halide preferentially via two kinds of binding interaction. The first one is characterized by an alkene-copper(I) interaction at the copper site, and the second a surface organometallic species at the tin site in which tin is in the +IV oxidation state.
