摘要

Abstract Isomeric 1-(fluoren-9-yl)-2-(2-methyl-5, 6-dihydrocyclopenta [f]-1 H-indenyl) ethanes 1a, b and C 1-symmetric metallocenes, viz., rac-1-(η 5-fluoren-9-yl)-2-(2-methyl-5, 6- dihydrocyclopenta [f]-η 5-inden-1-yl) ethanezirconium dichloride (9) and rac-1-(η 5-fluoren-9- yl)-2-(2-methyl-5, 6-dihydrocyclopenta [f] η 5-inden-1-yl) ethanehafnium dichloride (10), with these ligands were synthesized by modified procedures. The structures of compounds 1b ...
