## Abstract ^1^H chemical shifts of quinoline, quinoline __N__βoxide and the quinolinium ion were obtained by complete analysis of their NMR spectra and interpreted critically in an attempt to quantify the possible different effects acting on the shielding constant of protons in these systems. Semi

β¦ Synopsis
The recent paper 2) of Buchardt suggesting that the stable photo-products from 2-phenylquinoline l-oxides have the 4,5-hens-1,3-oxasepine structure (IB) rather than the oxaziridine structure (IA) prompted us to report the results of our study on this problem.

## Abstract The bridged aniline or 1βnaphthylamine derivatives 8β10 react with nitrous acid in the presence of perchloric acid to give the bridged diphenoquinone diiminium salts 12Β·2 HClO~4~, 17Β·2 HClO~4~, 19Β·2 HClO~4~ and 23. The same products are obtained from these substrates upon their reaction
