A user-friendly approach is presented to sidestep the venerable Grignard addition to unactivated ketones to access tertiary alcohols by reversing the polarity of the disconnection. In this work a ketone instead acts as a nucleophile when adding to simpleunactivatedolefins to accomplish the same overall transformation. The scope of this coupling is broad as enabled using an electrochemical approach
