Catalytic Oxidation of Triphenylphosphine with Nitrogen(I) Oxide in the Presence of Tetrakis(tert-butyl)phthalocyanine Complexes

摘要

In is known that the molecule of nitrogen(I) oxide is thermodynamically unstable with respect to its constituent elements (#DELTA#G_f~o 24.9 kcal/mol, #DELTA#H_f~o 19.6 kcal/mol).At the same time, the key reaction ofr the thermal decompositon of N_2O:N_2O(gas) -> N_2(gas) + O(gas)(~3P) (#DELTA#H~o (39.7 kcal/mol), is highly endothermic and has a high activation energy. As a result, nitrogen(I) oxide demonstrates a significant kinetic inertness to decomposition up to 500 deg C [1].
