Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Wehner, S, once mentioned the application of 2043-57-4, Name is 1,1,1,2,2,3,3,4,4,5,5,6,6-Tridecafluoro-8-iodooctane, molecular formula is C8H4F13I, molecular weight is 474, MDL number is MFCD00039410, category is iodides-buliding-blocks. Now introduce a scientific discovery about this category, Computed Properties of C8H4F13I.
Two consecutive Eley-Rideal reaction steps in a D atom adsorbate interaction: from methylene iodide via methyl iodide to methane
The interaction of gaseous D atoms with methylene iodide molecules adsorbed on graphite monolayer covered Pt(lll) surfaces was studied using direct product rate measurement. At 85 K methane was observed as a reaction product from two consecutive D/adsorbate reaction steps. Via D addition to methylene iodide, adsorbed methyl iodide is formed as an intermediate. Subsequently, D abstracts methyl from methyl iodide towards methane. Approaching and passing the methyl iodide intermediate desorption temperature of 135 K during the reaction, the desorption of the intermediate prevents methane production. The kinetics of methane and intermediate methyl iodide formation is in agreement with the operation of Eley-Rideal reaction steps. This is in accordance with the expectation that on a substrate with a flat adsorption well for atoms from the gas phase the Eley Rideal mechanism should operate in atom/adsorbate reactions.
