Abstract

Both endo- and exo-( η 6-1,4-dimethyltetrahydroquinoline)Ru(II)Cp·PF 6 complexes were found to undergo alkylation at the benzylic position upon treatment with NaH and an electrophile. The resulting benzylic quaternary carbon center was formed by reaction of the electrophile exclusively from the face opposite the CpRu(II) fragment regardless of the stereochemistry present in the starting complex. The stereoisomeric Ru(II) complexes of 1,3-dimethylindoline exhibit similar reactivity.
