A 1,2,4-diazaphospholyl radical and its nitrogen–phosphorus coupled dimer: synthesis, X-ray structural characterization, EPR analysis, and computational studies

This is the authors' abstract. We don't add key points for this paper.

The oxidation of 1,2,4-diazaphospholide potassium (K(+)[]) produces a neutral 1,2,4-diazaphospholyl radical () which can subsequently afford the (N)-(P) dimer involving a N-P linkage.
