Patent ID: 7737070

Claim:
A process for the preparation of a metal-organic compound, comprising at least one imine ligand, characterized in that an imine ligand 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 reagent of formula 2 in the presence of at least 1, respectively at least 2 equivalents of a base, with Y═N—R as formula 1, wherein Y is selected from a substituted carbon, or nitrogen 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 L 1 , L 2 , L 3 , and L 4 represent a ligand or a group 17 halogen atom on M and may be equal or different, X represents a group 17 halogen atom, k, l, m, n=0, 1, 2, 3, 4 with k+l+m+n+l=V.
