Solid-phase C-C and C-O bond forming reactions using 'traceless' pi-arene-chromium linkers.

The scope of solid-phase reactions utilizing a 'traceless' pi-arene-chromium linker has been expanded to include the addition of organo-lithium reagents to a supported ester group, generation and alkylation of an enolate anion, and substitution via the Mitsunobu reaction. Immobilization of ortho-disubstituted polyfunctionalized arene chromium dicarbonyl species onto the solid support and subsequent, selective transformation is also reported.
