| Abstract: | The novel aromatic ring compound 2,4‐diphospha‐3,5‐diaza‐thiole (cyclo‐SNPNP) was synthesized via flash pyrolysis of SP(N3)3 and characterized by IR spectroscopy and 15N isotope labeling. Quantum chemical computations indicate its formation by head‐to‐tail dimerization of SNP and subsequent elimination of a sulfur atom from the highly unstable boatlike six‐membered‐ring compound cyclo‐SNPSNP. |
