New perspectives are opened by the synthesis of 1,3‐diphospholide ions such as 2 from 1,2‐diphosphetenes like 1 . The Ph substituents of 2 are easily varied by choosing an appropriately substituted starting material; even the H atom in 2 is subject to replacement. Compound 2 reacts with a cationic cyclopentadienyliron species to give the corresponding terrocene analogue.
