## Abstract Perovskiteβtype oxides, ABO~3~, can be successfully applied as solid βoxygen reservoirsβ in redox reactions such as selective hydrogen combustion. This reaction is part of a novel process for propane oxidative dehydrogenation, wherein the lattice oxygen of the perovskite is used to comb

β¦ Synopsis
The reaction rates and selectivity of lower olefines formation in high temperature reactions, such as catalytic methane dehydrodimerization and catalytic pyrolysis of C, hydrocarbons are substantialy enhanced by oxygen and oxygen-containing compounds.

## Abstract Initial rates of formation of primary products have been measured in the pyrolysis of ethylene at 500Β°C, and a mechanism for the reaction is proposed based on the isomerization of the __n__βhexyl radical. Additions of oxygen in amounts less than 0.1% markedly increased the rate of forma
The oxidative alkylation of benzylic C-H bonds with 1,3-dicarbonyl compounds was developed using oxygen as the terminal oxidant in the presence of catalytic amounts of FeCl 2 , CuCl and NHPI.
