Heating a 2H-azaphosphirene complex in the solid
state afforded the first head-to-tail dimer, a
2,5-dihydro-2,5-diphosphapyrimidine complex, a
η1-diphosphene complex and another complex having
low-coordinated phosphorus centers; whereas the latter was detected only by
31P NMR spectroscopy, the dimer was isolated and structurally
characterized.

Synthesis of the first 2,3-dihydro-1,2,3-azadiphosphete complex was achieved via thermal reaction of a 2H-azaphosphirene complex in o-xylene, whereby a 2,5-dihydro-1,3-diaza-2,5-diphosphinine complex and a further unidentified byproduct were formed; the structure of the title compound was established through an X-ray single-crystal diffraction study.
