Cyclopropyl anion
WebThe ketyl anions of aryl cyclopropyl ketones with good radical stabilizing groups on the cyclopropane ring (class ID), including trans-1-benzoyl-2-phenylcyclopropane (66), and 1-benzoyl-2-vinylcyclopropane (76) undergo rapid unimolecular ring opening.

WebA method for intermolecular [3+2] cycloaddition between aryl cyclopropyl ketones and alkenes involving the combination of Lewis acid and photoredox catalysis is reported. In contrast to other more common methods for [3+2] cycloaddition, these conditions operate using a broad range of both electron-rich and electron-deficient reaction partners.
