Publikováno v: Russian Chemical Bulletin. 49:1287-1291
An efficient synthetic approach to 9,9-bis(cyclopentadienyl)fluorenes was developed. The two correspondingansa-zirconocenes were synthesized. The structure of one of these compounds was established by X-ray diffraction analysis.

Publikováno v: Russian Chemical Bulletin. 49:942-945
An efficient synthetic approach to 3-alkyl(aryl)-2-bromoindenes was developed. The reaction of 2-bromo-3-tert-butylindene with MeMgl catalyzed by Ni(dppp)Cl2 afforded 3-tert-butyl-2-methylindene from which bis(3-tert-butyl-2-methylinden-1-yl)methane

Autor: Igor A. Kashulin, I. V. Taidakov, Lyudmila G. Kuzmina, Ilya E. Nifant'ev, N. B. Ivchenko, Pavel V. Ivchenko
Publikováno v: Russian Chemical Bulletin. 49:724-727
Reactions of different cyclopentadienes with phorone were studied. Nonsubstituted and monosubstituted cyclopentadienes form annelation products,viz., 4,4,8,8-tetramethyl-1, 3a,4,5,6,7,8,8a-octahydroazulen-6-ones.

Synthesis of 1-(cyclopentadienyl)adamantane and the corresponding zirconium complexes
Autor: Ilya E. Nifant'ev, Pavel V. Ivchenko, N. B. Ivchenko
Publikováno v: Russian Chemical Bulletin. 49:508-513
An effective method for the synthesis of 1-(cyclopentadienyl)adamantane based on the reaction of 1-bromoadamantane with nickelocene in the presence of PPh3 was proposed. A number of organic derivatives and bis-cyclopentadienyl complexes of zirconium(
