| abstract |
The invention relates to a method of synthesizing a zirconocene dichloride complex of formula (8) ("compound (8)"):wherein R1, R2, and R3 are independently H or (C<sub>1</sub>-C<sub>4</sub>)alkyl, or R1 and R3 are bonded together to form a (C<sub>1</sub>-C<sub>4</sub>)alkylene and R2 is H or (C<sub>1</sub>-C<sub>4</sub>)alkyl, R4 is H or (C<sub>1</sub>-C<sub>4</sub>)alkyl, R5 is either H or (C<sub>1</sub>-C<sub>4</sub>)alkyl, R6 to R8 independently are H or (C<sub>1</sub>-C<sub>4</sub>)alkyl and R9 and R10 independently are H, (C<sub>1</sub>-C<sub>4</sub>)alkyl, or R9 and R10 are bonded together and are a (C<sub>3</sub>-C<sub>5</sub>)alkylene. |
