Htlckells (4n t c)n-electron rule prsdicts that borepin (I), which is isoelectronic with the tropylium ion (II), will be aromatic. However, all attempts to prepare borepin have failed (l-3). The dibenzo derivative (III) has been synthesized by Van Tamelen et a1.( ), but these authors do not make cle
