A stabilized enolate attached with a carbon tether to a cationic (eta (6)-a
rene)(RuCp)-Cp-II moiety was found to participate in an intramolecular SNAr
reaction to deliver Ru-coordinated 1-acetyl-2-tetralone. Nucleophilic arom
atic substitutions involving substituted beta -dicarbonyl nucleophiles proc
eeded with concomitant deacetylation to afford 1-alkyl-2-tetralone derivati
ves. The 2-tetralone products were found to be amenable to further stereoco
ntrolled elaboration via benzylic alkylation. (C) 2000 Elsevier Science Ltd
