Preparation and properties of 1-adamantylmethyl and adamantyl complexes of transition metals

Abstract

The syntheses and characteristic properties of a variety of 1-adamantylmethyl (R = 1-adme) compounds of transition metals are described. These include peralkyls, MR_n(M = Ti, V, Cr, Mn, or Zr); mixed complexes, MR_nX_m(X = OBu^t or Cl, M = V, Nb, or Ta); π-acid complexes, MR₂L₂(L = P- or N-donor) including the first example of a thermodynamically favoured trans-dialkylplatinum(II) derivative. Additionally, the preparations of bis(1- adamantyl)- and bis(2-adamantyl)-magnesium are reported, as well as successful and inconclusive attempts to produce Cr(ad)₄(ad = 1- or 2-adamantyl).
