## Abstract The title compounds have been isolated and their structures determined by X‐ray crystallography. Their relative stability is discussed in terms of theory and experiment. The __endo__‐adduct is the thermodynamically more stable one.
We previously reported the nmr spectrum of 1,4,7,7-tetrachloronorbornane; however, detailed analysis of the spectrum was precluded by its complexity, (8 spins). As an approach to the analysis of the nmr spectrum of 1,4,?-7-tetrachloronorbornane, we have selectively deuterated the 2-and 3positions, a
## Abstract The proton spectra of __exo__‐ and __endo__‐3‐thiatricyclo[4.2.1.0^2,5^]non‐7‐ene 3,3‐dioxide have been analysed and completely assigned. Considerations of coupling constants indicate that the thietane ring is nonplanar and that the norbornene residue is significantly distorted from the
## Abstract Alkalische Zersetzung der bis‐__p__‐Toluol‐sulfonylhydrazone **3** und **4** von sowohl __anti__‐ (**1**) wie auch __syn__‐Bis‐homo‐__p__‐chinon (**2**) ergab 4,5‐Homo‐1,7‐diaza‐inden (**5**). Das Produkt hat Eigenschaften eines Pyrazols und eines Olefins. Durch katalytische Reduktion e
