  Triphenylmethylcyclopentadiene Ph(3)CC(5)H(5) (1) and 2-[tris-(2'-methoxyphenyl)methyl]cyclopentadiene 2-((2'-CH3OC6H4)(3)C)-C5H5 (2) have been prepared in high yields via reactions of the corresponding triarylmethyl-halogenides with Cp(2)Ni (and CpSn(CH3)(3) in the case of 1). It is shown that 3-tritylsubstituted 6,6-dimethylfulvene formed exclusively in the reaction between the lithium salt of 1 and acetone. Cyclopentadiene 2 exists only as the 2-triarylmethylsubstituted isomer in a mixture of two enantiomeric forms caused by the C-3v-asymmetry type in the relative orientation of the aryl groups. Cyclopentadiene 1-Si(CH3)(3)-(3-Ph(3)C)-C5H4 was obtained by reaction of the sodium salt of 1 with (CH3)(3)SiCl; it crystallizes from hexane in the monoclinic space group P2(1)/c with cell dimensions a = 11.635(5), b = 12.400(7), c = 15.531(7) Angstrom, V = 2240.09(9) Angstrom(3) and Z = 4; the Si atom is in the allylic position with d(C-Cp-Si) = 1.891(8) Angstrom, Si-C(3)-C(2) = 109.7(6)degrees, Si-C(3)-C(4) = 110.3(6)degrees, C(2)-C(3)-C(4) = 100.2(7)degrees.

  The preparative synthetic routes to tritylcyclopentadienyl metal derivatives of sodium, tin and titanium have been studied. Molecular structures of Ph3CC5H4SnMe3 (3) and Ph3CC5H4TiCl3 (4) have been defined. The ClPh agostic interaction in the structure of 4 provides an unprecedented low reactivity of 4 to nucleophiles of different natures.
