Mixed-Ligand Arenechromium Carbonyl Complexes as Electronic Modulators
摘要:
A number of mixed ligand eta(6) 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 ar basicity is achieved, and results suggest that important vinylarene pi-pi interactions exist in acrylate derivatives of these chiral auxiliary systems.
