Deprotonation of di(3-methylindol-2-yl)phenylmethane (L2H 2) or 2-methoxyphenyldi(3-methylindol-2-yl)methane(L2′H2) with two equivalents of nBuLi, followed by reactions with Cp 2TiCl2 or Cp2ZrCl2 yielded complexes Cp2TiL2(1),Cp2TiL2′(2),Cp2ZrL2(3)andCp2ZrL2′(4). Compounds 1-4 were characterized by NMR spectroscopy, and compounds 1, 3, and 4 were further analyzed by X-ray crystallography and elemental analysis. The molecular structures of 1, 3, and 4 illustrate that chelating di(3-methylindol-2-yl) methanes have a structural relationship to coordinated bis(pyrazolyl)borates.
