Abstract: As a discovery of C—C coupling and amine elimination reaction by treatment of 6-dimethylamino-6-methylfulvene with zirconium tetrachloride, experiments using amino-substituted benzofulvene 1a or aminopentafulvene 2a, instead of 6-dimethylamino-6-methylfulvene, gave bis[1-(dimethylamino)ethenyl-indenyl]zirconium dichloride 1c which was characterized by X-ray diffraction as monoclinic, space group C2/c, a=2.0288(4) nm, b=0.9817(2) nm, c=1.4589(3) nm, β=115.73(3)°, V=2.6175(9) nm3, Z=4, R=0.0723, and bis[(1-methyl-4,5-dihydro-2-pyrrolnyl)cyclopentadienyl]zirconium dichloride 2c as triclinic, space group P1, a=0.80749(16) nm, b=0.94340(19) nm, c=1.4238(3) nm, α=91.04(3), β=97.41(3), γ=106.68(3)°, V=1.0286(4) nm3, Z=2, R=0.0800.
