Elm. Cowton et al., SYNTHESIS AND REACTIVITY OF TRICARBONYL(INDAN-2-ONE)CHROMIUM(0), Journal of the Chemical Society. Perkin transactions. I, (17), 1995, pp. 2077-2078
Stable crystalline tricarbonyl(indan-2-one)chromium(o) 1 has been synt
hesised from relatively unstable indan-2-one by ketone protection, chr
omium complexation and ketone deprotection; addition of non-basic nucl
eophiles to the ketone of 1 and deprotonation/alkylation procedures pr
oceed efficiently and stereoselectively to give good yields of diastet
eoisomerically pure products.
