Abstract
Chapter 4. The compounds dibenzoylmethane and N-phenylsalicylaldimine react with VOCl3 in toluene to generate complex V(O)Cl2(dbm) (dbm =C6H5C(O)CHC(O)C 6H5) and a complex of the empirical formula C13H 11Cl3NO2V. The square pyramidal complex V(O)Cl 2(dbm) is a black solid that is stable in solution, but reacts with trace water. The complex C13H11Cl3NO 2V is unstable in solution. In a solution of ether/hexane, V(O)Cl 2(dbm) reacts with NaOSiMe3 to yield the uncharacterized intermediate V(O)(dbm)(OSiMe3)2, which reacts with the organometallic dihydroxo complex [N(n-Bu)4][ cis-Os(N)(CH2SiMe3)2(OH)2] to generate Os(N)(CH2SiMe3)2(dbm).
