When heated in xylene the fused 1λ4,2-thiazines (3), with the exception of the benzo compound (3c) wich is thermally stable, rearrange to the 4aH-isomers (4).S-Phenyl groups migrate exclusively 1,4 to carbon with consequent disruption of the th

, p. 884 - 885 (2007/10/02)
The azathiabenzene derivatives (3), (7), and (11) rearrange on heating by a shift of the sulfur substituent to carbon rather than a shift to nitrogen, even though for ylides (3) this rearrangement involves loss of thiophen and furan aromaticit
