Über die Darstellung von Phosphoniumsalzen aus Yliden und den freien Säuren bzw. ihren Ammoniumsalzen

The Synthesis of Phosphonium Salts from Ylids and Free Acids or Their Ammonium Salts Tetramethylphosphonium-acetate, -hydrogendiacetate, -azide, -thiocyanate, -nitrate, -sulfate, and -thiosulfate have been prepared from trimethylmethylene phosphorane and the corresponding acids or their ammonium salts, with liberation of ammonia. The reactions were conducted in inert solvents or in alcohol/water mixture and yield pure products in high yields.
