    Notes: Abstract This paper is divided in two parts. In chapter one we generalize the concept of satellite for abelian categories, substituting Ext by an arbitrary functor E:A op×B→Ens. A very close relation to Kan functor extensions turns out. In chapter two we give a comprehensive formulation of the wellknown cohomology theories for groups and algebras-with the recently used modification in taking the group of derivations as the lowest cohomology group- starting with a categorical definition of the concept of singular extension. There is a zeroth chapter with a construction on functors, needed in both parts, and a third with examples.

    Notes: 4,7-Dichlor-chinaldin wird mit Hydrazin zum 4,7-Dihydrazino-chinaldin umgesetzt, dessen Reaktivität bei der Kondensation mit Aldehyden überprüft wird.Das unterschiedliche reaktive Verhalten der beiden Halogenatome im 4,7-Dichlor-chinaldin wird bei der Umsetzung mit Phenylhydrazinen und Semicarbazid studiert.Auch wird das 4-[4′-Methyl-phenyl-merkapto]-7-chlor-chinaldin in diese Untersuchungen einbezogen; zur Erhöhung der Aktivität des Halogenatoms am C7 wird voran-stehende Verbindung nitriert.Die Stellung der eingeführten Nitrogruppe wird infrarotspektroskopisch festgelegt.
