Synthesis of Fluorene Derivatives through Rhodium‐Catalyzed Dehydrogenative Cyclization

Abstract

Doubling up: Two CH bond activations took place efficiently upon treatment of 1 with a rhodium catalyst to form dehydrogenative cyclization products 2. Furthermore, 3 undergoes similar cyclization and subsequent decarboxylation through the cleavage of two CH bonds and one CC bond. Both reactions provide straightforward routes to the fluorene framework. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
