Ylide CpPMePh2 was synthesized by the deprotonation of Ylide salt of iodide by using different deprotonating agent like n butyl Li, NaH, (CH3)2N Li, isopropyl Li and ((CH3)3Si)2N.Li.  Out of all these deprotonating agents only ((CH3)3Si)2N.Li gave pure and better yield.  Its complex of Ru was synthesized. A RuCl2(PPh3)3 complex reacted with the freshly synthesized Ylide gave successful required ruthenium complex.  The synthesized [Ru(PPh3)3(CpPMePh2)2]Cl2 complex was analyzed and verified by 1H and 31P NMR.
