It is a colorless, air-sensitive liquid that is soluble in organic solvents. With the formula (CH2PMe2)2 is used as a compact strongly basic spectator ligand (Me = methyl), Representative complexes include V(dmpe)2(BH4)2, Mn(dmpe)2(AlH4)2, Tc(dmpe)2(CO)2Cl, and Ni(dmpe)Cl2. ==Synthesis== It is synthesised by the reaction of methylmagnesium iodide with 1,2-bis(dichlorophosphino)ethane: :Cl2PCH2CH2PCl2 + 4 MeMgI → Me2PCH2CH2PMe2 + 4 MgICl Alternatively but it can be generated by alkylation of sodium dimethylphosphide. The synthesis of dmpe from thiophosphoryl chloride has led to serious accidents and has been abandoned.〔J. E. Bercaw, G. W.
