We have reported an indium(0)-mediatedCsp3–S/Ocross-couplingapproach that leads to the highly regioselectivealkylation of α-enolic acetate/dithioacetate systems. This hetero cross-coupling reaction does not require additional co-catalyst or promoter, and the in situ generated organoindium species promotes the reaction by acting as the coupling partner of the α-enolic acetate/dithioacetate substrates
