  • Organometallic Chemistry
  • Materials Science

Background:

  • Small-cage compounds offer unique structural and electronic properties.
  • Group 15 elements present challenges in forming stable, complex structures.
  • Diphosphadiazanediyls are reactive biradicaloids with potential for novel synthesis.

Purpose of the Study:

  • To isolate new small-cage compounds composed solely of Group 15 elements.
  • To explore the reactivity of diphosphadiazanediyls in small molecule activation.
  • To synthesize novel hexapnicta-[2.1.1]bicyclohexane structures.

Main Methods:

  • Utilizing the reactivity of diphosphadiazanediyls.
  • Activation of small molecules with double bonds (diazenes, diphosphenes).
  • Isolation and characterization of the resulting cage compounds.

Main Results:

  • Successful isolation of new small-cage compounds containing only Group 15 elements.
  • Demonstrated the ability of diphosphadiazanediyls to activate diazenes and diphosphenes.
  • Formation of hexapnicta-[2.1.1]bicyclohexane derivatives.

Conclusions:

  • Diphosphadiazanediyls are effective reagents for constructing novel Group 15 cage compounds.
  • This work expands the scope of small-cage chemistry to include exclusively pnictogen frameworks.
  • The synthesized compounds may possess interesting electronic and structural properties for further investigation.
