dc.description.abstract | Low oxidation-state silicon compounds are fundamentally interesting for both academic research and industry. Phosphorus-substituted, two-coordinate congeners thereof are especially appealing, mostly for electronic reasons. However, they remain rare, with only the NHC-stabilized phosphasilenylidene (Im-Dipp2)Si=PMes* (1) reported in 2015 ( Although stable diphosphanosilylenes are highly desired compounds, they remain elusive despite several literature-reported synthetic attempts. In this work, a novel synthetic approach is followed featuring a Hückel-aromatic cyclic tetrylene design, similar to Arduengo carbenes, and a key late-stage salt metathesis at the oxidation state of Si(II). Thus, the first stable P-heterocyclic silylenes (PHSis) Si(PR(CH))2 ( This work also features the synthesis of the ß-phosphaenone TerMesPC(Me)C(Me)O ( | en |
