Abstract
Series of 2-(2-thio-3-methyl-6-substitutedamino)-
1,3,5-thidiazinoimino11-(pipr- azine-1-yl)dibenzob,f1,4
oxazepines IXB(a-h) was successfully synthesized by the
isomerisation of 2-(2-methylimino-6-substitutedamino)-1,3,5-
dithiozinoimino-11-(pipr azine-1-yl) dibenzo b,f1,4
oxazepines VIII(a-h) by 5% aqueous sodium bicarbonate in
ethanol medium. The structures of all synthesized compounds
were determined on the basis of chemical characteristics,
elemental analysis and spectral studies
