The phosphonium (more obscurely: phosphinium) cation describes polyatomic cations with the chemical formula PR+ 4 (R = H, alkyl, aryl, halide). The stability of the generated superoxide ion depended on the anion. 2 • ¯, while chemical generation was done by adding KO 2 to dimethylsulphoxide (DMSO). Its molar mass is … can be made longer. Phosphonium is an ion.It is rare. Abstract Phosphonium ions are shown to undergo a gas-phase Meerwein reaction in which epoxides (or thioepoxides) undergo three-to-five-membered ring expansion to yield dioxaphospholanium (or oxathiophospholanium) ion products. The possibility of designing a solvent/reagent for Wittig reactions from basic phosphonium salts is explored theoretically. Phosphonium ionic liquids of the present invention comprise cations as described above with anions that are generally selected from compounds that are easily ion exchanged with reagents or solvents of the general formula: In the suggested R4P+PhO– and Ph3PR+PhO– ionic liquids (ILs), the phenolate anion is prone to remove the α-proton from the alkyl chains, forming a phosphorous ylide.
