Reactivity of Low Valent Magnesium(I) Complexes with Epoxides and Episulfides. [PDF]
Angew Chem Int Ed EnglC–H functionalisation and ether cleavage are typically performed by aggressive organolithium reagents. Unveiling the untapped Brønsted basicity of magnesium‐oxo species, the reaction of Mg(I) precursors with epoxides initially proceeds via deoxygenation, followed by deprotonation and rearrangement of a second epoxide.
