6,13-Dibromo-6,13-dihydro-6,13-diborapentacene (1) has been prepared by the reaction of 2,3-bis(trimethylsilyl)naphthalene with BBr(3). The reaction of 1 with Me(4)Sn or mesityllithium afforded the dimethyl derivative 2 or the dimesityl derivative 3, respectively. In the solid state compounds 1 and 2 form cofacial pi-stacks along the a crystal axes, albeit in slightly different ways.
