A 1,2,4-diazaphospholyl radical and its nitrogen–phosphorus coupled dimer: synthesis, X-ray structural characterization, EPR analysis, and computational studies†
Abstract
The oxidation of 1,2,4-diazaphospholide potassium (K+[2−]) produces a neutral 1,2,4-diazaphospholyl radical (2˙) which can subsequently afford the 2(N)–2(P) dimer involving a N–P linkage.
