Direct Suzuki‐Miyaura Coupling of Naphthalene‐1,8‐diaminato (dan)‐Substituted Cyclopropylboron Compounds

Abstract

Abstract We herein describe the direct Suzuki‐Miyaura coupling of dan‐substituted, saturated organoboron compounds. Despite its Lewis acidity‐diminished character of the boron center, cyclopropyl‐B(dan) can be activated by t ‐BuOK to undergo transmetalation with a palladium complex. The increased s‐character of the C−B(dan) bond as compared with other alkyl‐B(dan) should be the key to the reaction. magnified image
