WebAbstract Iodotrimethylsilane which has a hard acid (Me 3 Si) -soft base (I) bond displays a strong oxygenophilicity towards ethers, esters, lactones, acetals, and other molecules involving oxygen atom as a functional group. Recent progress of the chemistry of iodotrimethylsilane is reviewed especially from a view point of organic synthesis. WebJan 1, 2024 · As reported by previous literature [ 13, 15, 16 ], Al has a higher oxygenophilicity, and Al2O3 possesses a lower Gibbs free energy. Therefore, from the kinetic analysis, Al elements are more likely to form oxide films than other elements (e.g., Ni, Co or Cr). Preferential oxidation of Al effectively delays the oxidation rate of other elements.
WebThe main driving force of hydrolysis is the high oxygenophilicity of ti- tanium and the formation of a stronger Ti-O bond (ΔH f298 = 662 kJ/mol) [14] compared to the Ti-Cl bond (ΔH f298 = 494 kJ/mol) [14]; therefore, it can be assumed that the replace- WebDec 1, 1997 · Carbanions of 2‐phenylpropionitrile were found to add to nitroarenes in liquid ammonia to form σH adducts, which were oxidized with KMnO4 to yield products of oxidative nucleophilic substitution of hydrogen (ONSH) in the position para to the nitro group.
