| Abstract: | The reaction of C6Cl5Ni(PPhMe2)2Cl with CHRCR′CH2MgX (X = Br or Cl) yields π-allylnickel compounds, (π-CHRCR′CH2)Ni(PPhMe2)C6Cl5 (Ia, R = R′ = H; Ib, R = H, R′ = CH3; Ic, R = CH3, R′ = H), which are stable in the solid state below ca. 150°C and are fairly stable in solution in the absence of oxygen. The π-allyl group was found by PMR spectroscopy to be rigid even in the presence of an excess of PPhMe2, P(OEt)3 or P(OMe)3. |
