Polyaromatic Compounds Containing Phosphinine Ring
06.09.2026
Many synthetic strategies attempt to vary the shape and size of the π‑conjugated system of carbon compounds to obtain optimal properties for the intended application. Recently, an alternative approach has come to the fore, which introduces a heteroatom (phosphorus) into the conjugated aromatic backbone, whose specific properties (chiral center on phosphorus, easy change of oxidation state, possibility of derivatization) significantly influence the behavior of the π‑framework. We aim to develop a simple and efficient synthetic approach based on our published method, which leads to phosphahelicene and introduces a phosphinine ring into the aromatic system. This approach is generalized and applied to synthesizing phosphanaphthalenes and phosphapolyaromatics based on phenacenes, helicenes, or nanographenes.
