From Nucleophilic to Electrophilic BCB Synthetic Equivalents: Hypervalent-Iodine-Mediated Umpolung Design
Bicyclo[1.1.0]butane (BCB) consists of two three-membered carbocycles that share a common bond. Because its geometry deviates substantially from conventional bond angles, the parent BCB is estimated to possess approximately 63.9 kcal·mol⁻¹ of ring strain[1].
