The synthesis, 13C-NMR spectroscopy and molecular structures of novel azathianthrene analogs

Syntheses of 2-azathianthrene (39), benzo[bl] ,4-diazathianthrene (51), 1,4-diazathianthrene (58), 1,3-diazathianthrene (62), l-oxo-1,2- dihydro-2,3-diazathianthrene (68), l-chloro-2,3-diazathianthrene (69) and 4-methoxy-l ,2-diazathianthrene (75) are reported. All of these compounds were analyzed with proton and carbon nmr spectroscopy. Both benzo[b]-l ,4-diazathianthrene (51) and 1,4-diazathianthrene (58) were also examined using X-ray crystallographic techniques. [...]
