  • Double ylide complexes of metals and process for making them
    Patent number: 4185028
    Abstract: Double ylide complexes of metals are made by reacting trimethylphosphin-imino-dimethyl-methylene phosphorane of the formula ##STR1## with one or more compounds of the metals nickel, palladium, platinum, gold, zinc, cadmium, aluminum, gallium, indium, thallium, magnesium or lithium.The novel double ylide complexes comprise various metal-bis[nitrido-bis(dimethylphosphonium methylides)], dimethyl-metal[nitrido-bis(dimethylphosphonium methylides)], and lithium-[nitrido-bis(dimethylphosphonium methylide)].

  • Trimethyl phosphinimino dimethyl methylene phosphorane and process for making it
    Patent number: 4083875
    Abstract: Trimethyl phosphinimino dimethyl methylene phosphorane of the formula: ##STR1## which is a novel chemical compound is produced. To this end, a tetramethyl phosphonium halide is reacted with 1.1 to 1.5 times the molar quantity of an alkali metal amide in an organic solvent, at 0.degree. to 35.degree. C, with the exclusion of air and moisture, and over a period of 24 to 72 hours. The reaction mixture is freed from residue and subjected to fractional distillation.
