A CLASSIFICATION OF THE PHOTOCHEMICAL ELECTROCYCLIC REACTIONS OF HETEROATOM CONJUGATED SYSTEMS
Kikuchi, O.
, p. 859 - 862 (1981)
Photochemical electrocyclic reaction mechanism of a variety of heteroatom conjugated systems has been elucidated by a unique concept.The proposed classification of the reaction, which is based upon the number and types of electrons involved in the reaction centers, takes into account the participation of the lone-pair electrons and gives the correct description of the electron behavior during the electrocyclic reaction process.

The gas-phase epoxidation of propylene using iron as a catalytically active metal has been studied. The XRD-amorphous silica nanopowder was found to host active as well as redox-silent iron species, using nitrous oxide as an oxidizing agent. The presence of iron oxide nanoparticles was proven in the most active catalysts, indicating that the epoxidation proceeds over nanoparticles rather than over isolated iron atoms. A combination of XPS, TEM and voltammetric techniques elucidated the mechanism of the formation of catalytically active forms of iron oxide, distinguishing selective forms from unselective and inactive ones in the epoxidation reaction. Transition response experiments showed a good correlation between epoxidation activity, N2O decomposition and electrochemical specification of iron oxides.
