| abstract |
The invention relates to a process for the preparation of a metal-organicncompound, comprising at least one imine ligand, characterized in that an iminenligand according to formula 1 or the HA adduct thereof, wherein HA represents an acid,nof which H represents its proton and A its conjugate base, is contacted with a metal-organicnreagent of formula 2 in the presence of at least 1, respectively at least 2nequivalents of a base, withn Y=N-R nwherein Y is selected from a substituted carbon, nitrogen, or phosphorous atom and Rnrepresents a substituent, and withn M v (L 1 ) k (L 2 ) I (L 3 ) m (L 4 ) n X nwherein:n 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 benequal or different X represents a group 17 halogen atom, k, l, m, n = 0, 1, 2, 3, 4 with k+l+m+n+1=V. n The invention further relates to a process for the preparation of anpolyolefin in the presence of the compound prepared according to the process of theninvention. |
