| Zur Existenz eines Triphosphacyclobutenid-Ions P3CH20 Contributions to the Chemistry of Phosphorus, 204 [1] On the Existence of a Triphosphacyclobutenide Ion P3C H 2e | | | | Abstract
| The structure o f the reaction product o f white phosphorus and sodium in diglyme which exhibits a low field AB2 system in the 31P {'H } N M R spectrum [4] has been reexamined. A c cording to the results o f a complete analysis o f its proton coupled 31P N M R spectrum (ABB'XX' system), the compound is the hitherto unknown 1,2,3-triphosphacyclopentadienide | | | |
