Patent ID: 7674867

Claim:
A one step process for the preparation of a metal-organic compound, wherein at least one imine ligand compound according to formula 1 or the HA adduct thereof, wherein HA represents an acid, of which H represents its proton and A its conjugate base, is contacted with a metal-organic regent of formula 2 in the presence of 1 or 2 equivalents of a base respectively, with Y═N—R as formula 1, wherein Y is selected from a substituted carbon, nitrogen, or phosphorous atom and R represents a substituent, and with M v (L 1 ) k (L 2 ) l (L 3 ) m (L 4 ) n X as formula 2, wherein: M represents a group 4 or group 5 metal ion V represents the valency of the metal ion, being 3, 4 or 5 L1, L2, L3, and L4 represent a ligand or a group 17 halogen atom on M and may be equal or different, at least one of the ligands L is chosen from cyclopentadienyl, C1-C20 hydrocarbyl, substituted cyclopentadienyls, indenyl, C1-C20 hydrocarbyl substituted indenyls, and halogen substituted C1-C20 hydrocarbyi substituted indenyls X represents a group 17-halogen atom, k, l, m, n=0, 1, 2, 3, 4 with k+l+m+n+1=V.
