Synthesis and reactivity of tricarbonyl(indan-2-one)chromium(0)
Abstract
Stable crystalline tricarbonyl(indan-2-one)chromium(0)1 has been synthesised from relatively unstable indan-2-one by ketone protection, chromium complexation and ketone deprotection; addition of non-basic nucleophiles to the ketone of 1 and deprotonation/alkylation procedures proceed efficiently and stereoselectively to give good yields of diastereoisomerically pure products.
