Reaction of hydrogen atoms with ethane

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1974
The reaction between hydrogen atoms and ethane has been studied in a flow-discharge system over the wide temperature range 503–753 K at pressures between 8 and 16 Torr. The major products are methane and ethane, reformed by methyl recombination. Minor products are propane and ethylene with traces of n-butane.The detailed mechanism has been established ...

Azide as a scavenger of hydrogen atoms

The Journal of Physical Chemistry, 1986
AbstractThe rate constant k1 has been determined by time‐resolved ESR measurements to be very high, 1.85·1O‐9 M‐1s‐1, confirming that the azide ion is an efficient scavenger of H atoms.

Hydrogen atom abstraction from HOOOCl by chlorine atom and OH radical

Inorganica Chimica Acta, 2007
Abstract Gas-phase reactions of HOOOCl with both Cl atom and OH radical are investigated using ab initio methods. The structures of all reactants, products, intermediates, and transition states have been optimized and characterized with the quadratic configuration interaction (QCISD) method.

Photochemical Deracemization of Lactams with Deuteration Enabled by Dual Hydrogen Atom Transfer.

Journal of the American Chemical Society
Photochemical deracemization has emerged as one of the most straightforward approaches to access highly enantioenriched compounds in recent years. While excited-state events such as energy transfer, single electron transfer, and ligand-to-metal charge ...

Abstract: Reaction of atomic hydrogen with chemisorbed species

Journal of Vacuum Science and Technology, 1976
Thermal hydrogen atoms produced at the surface of a hot tungsten filament react extremely rapidly with a tungsten film covered with ethylene or with ethylene decomposition products. For adsorption of ethylene at room temperature, where extensive loss of hydrogen occurs, the primary product is methane.

Directive effects in benzylic hydrogen atom abstraction—I

Tetrahedron, 1969
Abstract Relative reactivity values in benzylic bromination of alkylbenzenes and benzyl type ethers by 4-bromo-2,4,6-tri-t-butyl-2,5-cyclohexadienone (BTBC) have been measured by intermolecular competition with benzhydryl methyl ether as reference standard at 40° in CCl 4 are compared with results found for N-bromosuccinimide (NBS).
