Patent ID: 7655592

Claim:
A process for the preparation of a metal-organic compound, comprising at least one phosphinimine ligand, the process comprising contacting a HA adduct of a phosphinimine ligand compound according to formula 1 with a metal-organic reagent of formula 2 in the presence of at least 2 equivalents of a base, wherein HA represents an acid, of which H represents its proton and A its conjugate base, with Y═N—H as formula 1, and M v (L 1 ) k (L 2 ) l (L 3 ) m (L 4 ) n X as formula 2, and wherein Y is defined by the formula: wherein each R 1j , with j=1-3 is independently selected from the group consisting of a hydrogen atom, a halogen atom, a C 1-8 alkoxy radical, a C 6-10 aryl or aryloxy radical, an amido radical, or a C 1-20 hydrocarbyl radical unsubstituted or substituted by a halogen atom, a C 1-8 alkoxy radical, a C 6-10 aryl or aryloxy radical, an amido radical, a silyl radical of the formula: and a germanyl radical of the formula: wherein R 2j is independently selected from the group consisting of hydrogen, a C 1-8 alkyl or alkoxy radical, C 6-10 aryl and aryloxy radicals, each substituent R 1j or R 2j may be linked with another R 1 or R 2 to form a ring system, and 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, k, l, m, n=0, 1, 2, 3, 4 with k+l+m+n+1=V, and X represents a group 17 halogen atom.
