A new radical, 7-phenyl-1,3-bis(4-biphenylyl)-1,4-dihydro-1,2,4-benzotriazin-4-yl (2), was prepared from the iodo group-substituted benzotriazinyl radical 1 with phenyltriolborate salt by the Suzuki–Miyaura cross-coupling reaction at room temperature. An X-ray crystal structural analysis clarified its crystal structure. ESR measurements and DFT calculations revealed that its unpaired electron was more delocalized over the molecule than that of Blatter's radical due to the substituent effect.
