Tripyrrolidinophosphoric Acid Triamide as an Activator in Samarium Diiodide Reductions
The electrochemical and spectrophotometric characterization of the complex formed from samarium diiodide and 4 equiv of tripyrrolidinophosphoric acid triamide (TPPA) is presented. Kinetic studies indicate that the SmI2/TPPA complex possesses reactivity greater than the complex formed between samariu...

| Zusammenfassung: | The electrochemical and spectrophotometric characterization of the complex formed from samarium diiodide and 4 equiv of tripyrrolidinophosphoric acid triamide (TPPA) is presented. Kinetic studies indicate that the SmI2/TPPA complex possesses reactivity greater than the complex formed between samarium diiodide and 4 equiv of HMPA. Examples of the use of SmI2/TPPA in synthesis are presented. |
