2-Π- and 3-Π-Electron Diphosphorus-Containing 3-Membered Heterocycles
Résumé
The heterolytic cleavage of the P-N bond of the coordinated 1H-diphosphirene 5 gives the corresponding diphosphirenylium complex 6, while the homolytic cleavage of the P-N bond of the free 1H-diphosphirene 4 affords the transient diphosphirenyl radical 7 and the ensuing stable dimer 8 which features original half P-P bonds.
