Editing Ylide (section)

==Non-symmetric phosphorus ylides==
The a-keto stabilized ylides derived from bisphosphines like [[dppe]], [[dppm]], etc., viz., [Ph<sub>2</sub>PCH<sub>2</sub>PPh<sub>2</sub>]C(H)C(O)R and [Ph<sub>2</sub>PCH<sub>2</sub>CH<sub>2</sub>PPh<sub>2</sub>]C(H)C(O)R (R = Me, Ph or OMe) constitute an important class of hybrid ligands containing both [[phosphine]] and ylide functionalities, and can exist in ylidic and enolate forms. These ligands can therefore be engaged in different kinds of bonding with metal ions like [[palladium]] and [[platinum]].<ref>{{cite journal |first1=Seyyed Javad |last1=Sabouncheia |first2=Mohsen |last2=Ahmadi |first3=Zahra |last3=Nasri |first4=Esmaeil |last4=Shams |first5=Sadegh |last5=Salehzadeh |first6=Yasin |last6=Gholiee |first7=Roya |last7=Karamian |first8=Mostafa |last8=Asadbegy |first9=Sepideh |last9=Samiee |title=Synthesis, characterization, thermal, electrochemical, and DFT studies of mononuclear cyclopalladated complexes containing bidentate phosphine ligands and their biological evaluation as antioxidant and antibacterial agents |journal=[[Comptes Rendus Chimie]] |volume=16 |issue=2 |year=2013 |pages=159–175 |doi=10.1016/j.crci.2012.10.006|url=https://comptes-rendus.academie-sciences.fr/chimie/articles/10.1016/j.crci.2012.10.006/ }}</ref>
