Ethylene[bis(tri-o-tolyl phosphite)]nickel(0)

The preparation and properties of ethylene[bis(tri-o-tolyl phosphite)]nickel(0) are described. The ethylene appears in the proton nmr spectrum at τ 8.06, 3.3 ppm to high field of free C2H4. The v(C=C) of ethylene in the complex was observed in the Raman spectrum at 1487 cm-1, 136 cm-1, lower than that of free C2H4. Spectrophotometric measurements show that addition of tri-o-tolyl phosphite to a solution of the ethylene complex rapidly converts it to tris- and tetrakis(tri-o-tolyl phosphite)nickel complexes. The equilibrium constant K1, to give the tris-phosphite complex via the reaction (C2H4)-NiL2 + L ?K1NiL3 + C2H4, has a value of 6.8 ± 0.5 × 10-3 in benzene at 28°.
