A pyridinylidene carbene dimer effects reductive cleavage of C-O σ-bonds in acyloin derivatives, which represents the first cleavage of C-O σ-bonds by a neutral organic electron-donor. The methodology is applicable to a large array of substrates and the reduced products were isolated in good to excellent yields.
