Mixed-Ligand Arenechromium Carbonyl Complexes as Electronic Modulators

A number of mixed ligand η6 arenechromium carbonyl complexes have been prepared and investigated for their ability to effect electronic modulation of arene chemistry. In the case of an aniline-derived system, the arenechromium carbonyl complex is able to modulate the inductive capacity of the aniline nitrogen atom and thus, regulate its anchimeric ability. In the case of 8-phenylmenthol and benzyloxazolidinone derivatives, modulation of arene π basicity is achieved, and results suggest that important vinylarene π-π interactions exist in acrylate derivatives of these chiral auxiliary systems.
Fluorinated alcohols as solvents for Diels-Alder reactions of chiral acrylates

Fluorinated alcohols increase the rates of endo/exo selectivities of the Diels-Alder reactions of cyclopentadiene with (-)-menthyl and (-)-8-phenylmenthyl acrylates. The use of fluorinated alcohols also increases the diastereofacial selectivity in the reactions of (-)-menthyl acrylate, but decreases it when the dienophile is (-)-8-phenylmenthyl acrylate. These facts are accounted for by the conformational preferences of the dienophile in non-HBD solvents and by the tendency of fluorinated alcohols to shift the conformational equilibrium towards the s-trans conformation.
