| Uber die Bildung von N,N-Bistrifluormethylhydroxylammoniumsalzen (CF3)2N(X)OX+MF6-(X = H, D; M = As, Sb) On the Formation o f N,N-Bistrifluoromethylhydroxylammonium Salts (CF3)2N(X)O X+MF6-(X = H, D; M = As, Sb)  | | | | Abstract
| The preparation of the N,N-Bistrifluoromethylhydroxylammonium hexafluorometallates (CF3)2N(X)OX+MF6~ (X = H, D; M = As, Sb) is reported. The new compounds were cha racterized by IR, Raman, Mass, 'H , ,9F and l3C NM R spectroscopy. In addition we present our approach to the preparation of H-subsituted N,N-Bistrifluoromethylhydroxylammonium hexafluorometallates (C F ^ N (Y)O H +M F6~ (Y = C H 3, Cl, F; M = As, Sb). | | | |

| ,3-Dioxolane von N-substituierten 4-Piperidonen als Dehydrierungssubstrat 1,3-Dioxolanes of N-Substituted 4-Piperidones as Substrates for Dehydrogenations | | | | Abstract
| The applicability of ketals was examined for masking the carbonyl group in N-tertiary 4-piperidones during the dehydrogenation using mercury-edta. Various 1,3-dioxolanes showed a different behaviour in dependence on the N-substituent. With simple aliphatic moieties mainly dehydrogenated but hydrolyzed products were received. These enaminones were also available from the dehydrogenations of the corresponding 4-piperidones. Similar applied to para-acyl-aromatic substituted derivatives but with less yields. Aromatic substituents bearing a neighbour group on ortho-position with participation gave rise to different oxidation products partially with preservation of the ketal structure. | | | |
