Organische Phosphorverbindungen VIII. Die direkte Synthese von Alkyl‐ und Aryl‐halogenphosphinen

The reaction of methyl chloride, methyl bromide, methyl iodide, trifluoro‐methyl iodide, ethyl chloride, ethyl bromide, butyl bromide, and phenyl bromide with red phosphorus has been studied under a variety of conditions. In additon, the reaction of white phosphorus with methyl bromide and phenyl bromide is also described. The synthesis and properties of RPX2 (R = CH3, CF3, C2H5, C6H5, C6H5; X = Cl, Br, I) and R2PX (R = CH3, CF3, C6H5; X = Cl, Br) are reported. The reactions of RPX2 and R2PX With sulfur and with dimethylamine are also described.
