A tetravalent phosphorus atom in an aromatic system! A 1‐methylphosphininium tetrachlorogallate is synthesized and fully characterized (see structure). This compound has aromatic properties like those of phosphinine, pyridine, and pyridinium salts. These features were asserted and quantified by DFT calculations. This phosphininium salt reacts easily with an alkyne to yield a phosphabarellenium salt through a Diels–Alder reaction.
