Abstract: The oxidations of the amine complexes R u (~~~)~(AB)~+(where AB= ampy [2- (aminomethyl) pyridine], d2-ampy [2-(1, l-dideuterioaminomethyl) pyridine], and Meampy [2- (1-aminoethy1) pyridinel and bpy= 2, 2'-bipyridine) in aqueous solution to the corresponding imine species have been studied by using flash photolysis techniques. The rate-determining step of the reaction involves removal of a hydrogen from the a-carbon atom and the ...
