Bridged AzoalKanes- Thermal rearrangement of the diazene N-oxides (77) gives ultimately benzaidehyde oxime and HCN vie (78) and (79).78 Photolysis converts (80) into (81) by (2+21 cyoloaddition followed by retro-(2+21 cyclo-addition. 78... [Pg.495]

An ideal system in which to make these comparisons would appear to be phenyltriphenylmethyldiazene, 2 and the corresponding N-oxldes. Oxidation of the diazene with peroxytrifluoro-acetic acid affords a diazene N-oxide, assigned structure 3 on the basis of spectroscopic data (principally, ultraviolet... [Pg.128]

How does the rate of decomposition of diazene N-oxide 7 compare with the corresponding diazene, Direct measurement of the rate of decomposition of methyl benzhydryldiazenecarboxylate, Sy was complicated by tautomerization to the corresponding hydra-zone, Ph2C=NNHC02CH3. The rate of decomposition of was estimated from the measurement rate of decomposition of benzhydryl-phenyldiazene (24) and the observation that the rates of decomposition of phenyltriphenylmethyldiazene and methyl triphenyl-methyldiazenecarboxylate are the same (21). Relative rates of 7, 8, and a related nitrone, 9 (25) are summarized below. ... [Pg.131]
