A straightforward synthetic route to a novel phosphorus–carbon heterocycle, namely, phosphaindazole, which is the phosphorus analogue of indazole or indene, was developed from sodium tetraphosphanediide [Na 2 (P 4 Mes 4 )](Mes = 2,4,6‐Me 3 C 6 H 2 ) and n BuLi. A proposed intermediate in this reaction, the dimesityldiphosphanide dianion, could be isolated and structurally characterized as [Na 8 (thf) 8 (P 2 Mes 2 ) 4 ] · 2THF.
