A bunch of boroles: Two and three borolyl units were attached to a benzene ring (see figure). The adduct chemistry of these oligoboroles was found to be strongly dependent on the electronic and steric properties of the pyridine base that was employed. The degree of Lewis acidity of the oligoboroles was examined by base-transfer reactions.
