Abstract
3-Methyl-7-nitro-2,1-benzisoxazole is converted by trimethylphosphite into 4-acetylbenzofurazan. The preparation is described of several indazoles and benzotriazoles as possible precursors for analogous rearrangements. 1,10-Phenanthroline 1-oxide fails to undergo intramolecular oxygen transfer.Keywords
