| titleOfInvention | Process for the preparation of titanium complexes |
| abstract | A new process is disclosed, particularly simple, convenient and practical, for the direct synthesis of titanium complexes of the formula (I): (D)(ZR<1>m)n(A)TiLpXq, wherein (ZR<1>m)n is a divalent group bridging D and A; D is a delocalized pi-bonded moiety, which is bound in an eta<5 >bonding mode to Ti, and is preferably a Cp moiety; A is -O-, -S-, -N(R<2>)- or -P(R<2>)-, wherein R<2 >is hydrogen, alkyl, cycloalayl, aryl, alkylaryl or arylalkl; L are monoanionic sigma ligands selected from alkyl, cycloalkyl, aryl, alkylaryl and arylalkyl groups; m is 1 or 2; n is 1-3; p is 1 or 2, q is 0 or 1 and p+q=2; said process comprises reacting a ligand of formula (H-D)(ZR<1>m)n(A-H) with about 1 molar equivalent of TiX4 in the presence of about (2+p) molar equivalent of LjB or LMgX wherein X is halogen or -OR', B is an alkaline or alkaline-earth metal, and j is 1 or 2. |
