  • Beschreibung: Synthesis, Structure, and Reactivity of DiphosphiranesThe 1,1‐diamino‐1,2‐diphospha‐2‐propen (2,6‐Me2C5H8N)2P – PC(SiMe3)2 (3) is obtained by treatment of bis(2,6‐dimethyl‐piperidino)(trimethylsilyl)phosphane (1) with [bis(trimethylsilyl)methylene]chlorophosphane (2). Compound 3 readily undergoes thermally isomerization to the diphosphirane 2,6‐ Nucleophilic substitution of the P1‐chloro function of 1‐chloro‐2‐(diisopropylamino)1‐3,3‐bis(trimethylsilyl)diphosphirane (6) leads to alkyl, amino, phosphanyl, and arsanyl derivatives 7a – d. The corresponding hydrogen derivative 7e is formed by reduction of 6 with tri‐n1‐butylstannane. The molecular structure of 7c as well as the NMR data of the diphosphiranes are discussed.
