En Suite Generation of Chromium Carbonyl Arene Complex Substituted Propargylic Cation and Anion Intermediates in Side-Chain Functionalizations

The (phenyl)Cr(CO)3 substituent efficiently stabilizes both propargyl cations and anions. In subsequent trapping reactions of the anionic species that can be spectroscopically studied, the regioselectivity depends on the hardness of the attacking electrophile.
