Reaction of decamethylmetallocene cations [Cp-2*M](+) (M = Sc, Ti, V) with acetone and benzophenone resulted in the formation of the corresponding acetone adducts [Cp-2*M(OCMe2)(n)](+) (M = Sc, n = 2; M = Ti, n = 1; M = V, n = 1) and benzophenone adducts [Cp-2*M(OCPh)](+). The stoichiometry of these adducts is determined by both the electronic configuration of the metal center as well as steric pressure imparted by the large Cp*-ligands. In addition, the M-O-C angle is controlled by the number of free valence orbitals of the Cp-2*M unit. (C) 2011 Elsevier B.V. All rights reserved.
