Abstract: Twelve bulkier substituted titanocene and zirconocene dichlorides have been synthesized by reactions of 6,6-dialkyfulvenes with 1-lithiocycloheptene followed by treatment with MCl4(M=Ti, Zr), Their 1H NMR, EIMS and IR spectra have been discussed.

Key words: lithiocycloheptene, fulvene, addition reaction, substituted cyclopentadienyl metal compound, spectral behaviour
