Abstract:
Studying the axial ligation behavior of metalloporphyrins with nitrogenous bases helps to better understand not only the biological function of heme-based protein systems, but also the catalytic properties of porphyrin-based reaction sites in other biomimetic synthetic support environments. Unlike iron porphyrin complexes, little is known about the axial ligation behavior of Mn porphyrins, particularly in the solid state with Mn in the +3 oxidation state. Here, we present the syntheses and crystal and molecular structures of three new high-spin manganese(III) porphyrin complexes with the diffe

Abstract:
The background that led to the development ofthe first catalytic and enantioselective carbon-fluorine bond-forming reaction is presented. Two different approaches, i.e. the use of nucleophilic and electrophilic fluorinating agents, respectively, have been pursued. Well-defined RU(II) 16-electron systems of the type [RuF(PP)2]+ (where PP is a chelating diphosphine), as well as analogous complexes containing tetradentate PNNP ligands, were found to catalyze the halogen exchange reaction of activated alkyl chlorides, bromides, and iodides in the presence of TIF as the fluorine source.
