Bismabenzene (C5H5Bi) is the parent representative of a group of organobismuth compounds that are related to benzene with a carbon atom replaced by a bismuth atom. Bismabenzene itself has been synthesised but not isolated because it is too reactive, tending to instead dimerize in a Diels-Alder addition.[1][2][3]
An unstable derivative with 4-alkyl substituents was reported in 1982.[4] A stable derivative, with two ortho tri(isopropyl)silyl substituents, was synthesized from aluminacyclohexadiene, bismuth trichloride, and DBU in 2016.[1][5]
