| Chemilumineszenz der S02-Oxidation Chemiluminescence of SO2-Oxidation  | | | Abstract
| The reactions of diluted aqueous solutions of SO2 resp. HSO3-ions with MJ1O4-or Ce 4+ ions in the pH range 1-4 produce chemiluminescence in the spectral region of 450-600 nm. Measurements of the time course of the light emission and their simulation on an analog computer led to a reaction scheme in which a recombination product of primarily formed HSO3 radicals -of a lifetime of about 1 second -appears as precursor of electronically excited SO2 molecules. The participation of singlet oxygen can be excluded because at least the reaction with Ce 4+ ions proceeds also in the absence of oxygen. | | |

| Cyclodiaza-A 6 -thianes  | | | Abstract
| From sulfurtriimides and N-perfluoroalkyl-isocyanates or -sulfinyl-amines SSS'S'-tetra-imino-(lla-c), SS'-dioxo-SS'-di-imino-(19 and 28), and SSS'-tri-oxo-S'-imino-cyclodiaza-A 6 -thianes (34) were prepared. The structures of lib, 19 and 28 are discussed, general rules for the stability of these ring systems are derived. | | |
