摘要

Neutral organic electron-donor 7, formally a pyridinylidene carbene dimer, effects reductive cleavage of C− O σ-bonds in acyloin derivatives Ar (CO) CRR′ OX (X= OAc, OPiv, OBz, OMs) and this 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 counterparts were isolated in good to excellent yields. For certain substrates, donor 7 ...
