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.
