Base metal catalyzed dehydrogenation of formic acid and alcohols The content of this thesis is about base metal catalyzed dehydrogenation reactions and it contains two parts. In the first part a cobalt catalyzed formic acid dehydrogenation in aqueous media is disclosed. The second part deals with a manganese catalyzed dehydrogenation of alcohols which was developed by in situ combination of manganese pentacarbonyl bromide with phosphine free oxamide ligands.<eng>
