Abstract

Only strong Lewis acidic, arene-solvated Me3 Si+ ions react with E(SiMe3 )3 compounds (E=P, As) to give the crystallographically characterized E(SiMe3 )4+ onium ions 1 (left hand picture), which contain highly negative polarized P and As atoms, respectively. The masked Me3 Si+ ions in 1 can be easily transferred to Et2 O, to give the first structurally characterized planar silyloxonium ion [Et2 (Me3 Si)O]+ 2 (right hand picture).

Abstract

The complex LiAl(PH2)4 functions as an excellent nucleophilic transfer reagent for the phosphanyl group (PH2), as was shown by its reaction with SiCl4 and GeCl4 to give tetraphosphanylsilane and tetraphosphanylgermane, resp. Tetraphosphanylsilane was characterized by 1H, 31P and 29Si NMR spectroscopy and x-ray crystallog. (monoclinic, space group P21/c, R1 = 0.0479).
