Phosphole is the organic compound with the chemical formula C 4H 4PH; it is the phosphorus analog of pyrrole. The term phosphole also refers to substituted derivatives of the parent heterocycle. These compounds are of theoretical interest but also serve as ligands for transition metals and as precursors to … See more Unlike the related 5-membered heterocycles pyrrole, thiophene, and furan, the aromaticity of phospholes is diminished, reflecting the reluctance of phosphorus to delocalize its lone pair. The main indication of … See more The parent phosphole was first described in 1983. It was prepared by low-temperature protonation of lithium phospholide. Pentaphenylphosphole was reported in 1953. … See more • Benzophosphole • Metallole • Organophosphorus compound • Phosphorine, C 5H 5P See more The behavior of the secondary phospholes, those with P−H bond, is dominated by the reactivity of this group.
