benzophenone (BP) with a catalytic amount of Cu(OAc)2 . Under mild and operationally simple conditions, the Giese adducts resulting from the C(sp3 )-Hfunctionalization of amines, alcohols, ethers, and cycloalkanes could be synthesized. Preliminary mechanistic studies have revealed that the reaction does not proceed through a radical chain, but through a dual BP/Cu photocatalytic process, in which both CuII
Enolates generated from α-bromo esters by the reduction with “Bu6CrLi3” react with oxiranes to afford γ-hydroxy esters and β-hydroxy esters, depending on the Lewis acid used as a promoter.
