Abstract:	ansa{·⁵,·⁵′-1,1′-(1-silacyclopent-3-ene-1,1-diyl)bis(indenyl)]} dichlorozirconium (1a,b) was synthesized. The crystal structure ofmeso-(1,4-CH₂CH=CHCH₂)Si(C₉H₆)₂ZrCl₂] (1b) was established by X-ray diffraction analysis. Photoinduced interconversion of the racemic (1a) andmeso forms was studied under various conditions. The photostationary state (rac: meso=55∶45) was established rapidly when solutions ofansa-zirconocene were irradiated with visible light. Deceased Translated fromIzvestiya Akademii Nauk.
