ABSTRACT:
Substrates are oxidized by means of two-oxidative addition reactions of a dimeric, dinuclear transition metal complex oxidant containing four binucleating diisocyanide bridge ligands. The complex is reoxidized by means of a secondary oxidant which is a stronger oxidizing agent than the complex which in turn is oxidized by molecular oxygen. Though the direct oxidation of the complex by oxygen involves a large energy barrier and is relatively slow, the kinetics of the two stage oxidation of the complex by the secondary oxidant and of the oxidant by oxygen permit regeneration of the oxidant at reasonable rate. Substrates, such as the olefins, ethylene or propylene, have been continuously oxidized by bubbling oxygen and the olefin through a solution of a dimeric, dirhodium complex containing four 1,3-diisocyanopropane bridge ligands and a secondary oxidant such as a cerium salt.
