Abstract
The Beckmann rearrangement of dihydrosilazatone oximes yields benzopyridosilaazepinones which are isomeric relative to the position of the amide fragment in the central ring. One of these isomers is converted upon thermolysis at 250 °C to the lactam of o-(3-aminopyridyl-4)benzoic acid. The reduction of benzopyridosilaazepinones yields benzopyridosilaazepines.
