Abstract

The title compound is available in a non-hazardous, high-yield two-step procedure. Tri(sodium/potas-sium)heptaphosphide is prepared from red phosphorus and the liquid Na/K alloy in boiling monoglyme, and reacted further with chlorotrimethylsilane in toluene at - 50°C to give an 80% isolated yield of (Me3Si)3P7.
