The 70 eV electron ionization mass spectra of six cyclohexane fused 2- N -methyliminoperhydro-3,1-oxazines and six related thiazines were recorded and their fragmentation behaviour studied by metastable-ion analysis and exact mass measurement. For the unsubstituted compounds, decompositions which ...

Conformational changes of perhydro-1,3,2-dioxazine in open single-walled carbon nanotubes have been studied by hybrid DFT PBE/3z method. It was established that relative stability of equatorial and axial chair conformers of encapsulated molecule has been inverted, the latter form becoming favorable...
