  Abstract: The group 2 complexes   [(Me3Si)(i-Pr2P)N]2M(THF)x (M = Mg, x = 1; M = Ca/Sr, x = 2) as   well as an unusual dimagnesium complex   {[(Me3Si)(i-Pr2P)N]3Mg}MgBu have been prepd. and characterized by   multinuclear NMR spectroscopy and single crystal x-ray   diffraction. Each complex reacts with CO2 under extremely mild   conditions (15 min, 1 atm, room temp.) to give the isocyanate   (i-Pr)2P-N:C:O. The independent syntheses of (i-Pr)2P-N:C:O and   the carbodiimide dimer [(i-Pr)2PNCNP(i-Pr)2]2 are also reported.   [on SciFinder(R)]
