Abstract
Cyclobutene ozonide (2,3,7-trioxabicyclo[2,2,1]-heptane) containing D and $^{18}O$ enrichment was prepared by ozonolysis of cyclobutene and by singlet oxygen addition to furan. From the assignment of four isotopic species. It was established that the ozonide has $C_{s}$ symmetry. The peroxy bond distance is 1.489(1)A which is elongated about $^{S} 0.03A$ compared to less strained monocyclic ozonides. The singlet oxygen synthesis also leads to cyclobutadiene ozonide (2,3,7-trioxabicyclo[2.2.1]-hept-5-ene). This species was recently isolated and its MW spectrum (normal species) was assigned. The current status of its analysis will be discussed.
