An Isolable Mixed P,S-Bis(ylide) as an Asymmetric Carbon Atom Source

摘要

The transformation of molecules by introduction of atomic elements is one of the most fundamental reactions in chemistry. Indeed, the reactions of atomic hydrogen (reduction, hydrogenation) and oxygen (oxidation, epoxidation) are exceedingly important in organic synthesis, and numerous reagents and catalysts for this purpose are available. In marked contrast, the manipulation of atomic elements with a higher valence number, such as nitrogen and carbon, remains a more difficult task.
