Synthese und Charakterisierung von binären Molekülverbindungen der Gruppe 15 Elemente mit P2As2-, PSb2-, PBi2-, PBi3- und P2Bi4-Gerüst

Overview & Synopsis

The reactions of tBuPh2SiPLi2 with (Me3Si)2CHAsCl2 in molar ratio 1:1 yields the compound [(SiMe3)2CHAsPSitBuPh2]2 (1). The structure of 1 reveals the formation of a As2P2 ring compound. In contrast, the reactions of tBuPh2SiPLi2 with (Me3Si)2CHSbCl2 or (Me3Si)2CHBiCl2 yield the chloro bridged species [tBuPh2SiP{SbClCH(SiMe3)2}2] (2) and [tBuPh2SiP{BiClCH(SiMe3)2}2] (3). Starting from RMe2SiPLi2 (R = Thex, Me) the compounds [P{BiClCH(SiMe3)2}3] (4) and [P2{BiClCH(SiMe3)2}4] (5) were obtained from the reactions with (Me3Si)2CHBiCl2. The Compounds 1–5 were characterised by single crystal X-Ray diffraction, elemental analysis as well as IR and NMR techniques.
