| Abstract: | The bulkily substituted zirconocene dichloride complexes of the type RCpCpoZrCl2 Cpo＝2-MeOArCR1R2Cp, R1, R2＝CH3, C2H5, (CH2)5, etc.] have been synthesized by the reaction of 6, 6-dialkylfulvene with 2-MeOArLi followed by treatment with RCpZrCl3•DME (R＝H, Me, i-Pr), and all the complexes were characterised by 1H NMR, IR, MS and elemental analysis. A new type of intramolecular elimination reaction was found and anisole was eliminated from the complexes with formation of alkenyl-substituted zirconocene. |
