摘要:
The reaction of planar-chiral cyclopentadienyl-ruthenium complexes with allyl chloride at room temperature resulted in the diastereoselective formation of pi-allyl-ruthenium complexes, in which the chirality at the Ru center depended on the substituent at the 4-position of the cyclopentadienyl group. Epimerization at the Ru center of pi-allyl complexes at 90 degreesC suggested that the diastereoselectivity was under kinetic control.
