products. Ten of these were identified and together account for 70% of the total yield. The proposed reaction mechanism implicates the corresponding O-acetyl-hydroxylamine 15 as an intermediate. Attempts to prepare O-esters or O-ethers of aromatic hydroxylamines by dehydrogenation, with quinones, of the corresponding oximino-derivatives of oxo-1,2,3,4-tetrahydro-naphthalene and oxo-1,2,3,4-tetrahydro-phenanthrene

From the reaction mixture of the dehydrobormination of 1 - bromo - 4 benzoyloxyimino - 1,2,3,4 - tetrahydrophenanthrene (1) with 1,8-diazabicyclo [5.4.0] undec-7-ene (DBU) in benzene and in heavy atom solvents several products were isolated and their structures elucidated. The origin of the majority of compounds has been considered via the labile O-benzoylhydroxylamine 12, except product 11. The generation
