| 1. | The product contains the phosphonium cation [ HPPh 3 ] +.
|
| 2. | It is also easily alkylated to give phosphonium derivatives RPMe 3 +.
|
| 3. | The phosphonium salts have been traditionally used for peptide synthesis.
|
| 4. | Important chiral cation scaffolds are quaternary ammonium cations and quaternary phosphonium cations.
|
| 5. | The hydride is lithium aluminium hydride and the leaving group a phosphonium salt.
|
| 6. | They also are derived from phosphonium salts, but by deprotonation not alkylation.
|
| 7. | Reduction, iodination, and treatment with triphenylphosphine led to the phosphonium salt.
|
| 8. | Mechanisms differ for aliphatic and aromatic aldehydes and for aromatic and aliphatic phosphonium ylides.
|
| 9. | Unlike phosphonium ylides, the dialkylphosphate salt byproduct is easily removed by aqueous extraction.
|
| 10. | His early work was the study of phosphonium and phosphine derivatives and allied ammonium compounds.
