A series of 2-alkylindene (2-RInd; R= Me, i-Pr, n-Bu, Bzl, Cy, t-Bu) were prepared by nucleophilic addition of the corresponding alkyl anions to 2-indanone in the presence (or absence) of LaCl3. With these 2-alkylindenes, bis (2-alkylindenyl) zirconium dichloride complexes were synthesized to investigate the effects of alkyl substituents at 2-position of indene on the rotational conversion rate between rotamers (racemic and meso) and the ...
