Low cost renewable waste rice husks (RH) have been used as a support for grafting of an oxo-vanadium Schiff base via covalent attachment for the oxidation of tertiary amines to N-oxide. The synthesis of the desired RH grafted oxo-vanadium complex involves prior functionalization of the RH support with amino-propyltrimethoxysilane (APTMS) followed by its reaction with salicylaldehyde to get an RH-functionalized

(2-hydroxyethyl)amine- N -oxides isomers, their protonated forms, and H-complexes with acids have been studied in gas phase and DMSO solution by the quantum chemical calculations using DFT and MP2 methods. It is found that the proton affinity of the endo isomers 1a – 3a , exo isomers 1b – 3b and epi isomer 1c depends on the number of the hydroxyethyl groups, steric factors and strengths of the intramolecular H-bonds

⎯ (previously O=NR3 or O → NR3) continue to attract interest of synthetic, theoretical, and applied chemists. They are already used in cosmetics, as bio medical agents, and as oxidants in a number of organic reactions (catalytic epoxidation and dihydroxylation of alkenes, catalytic oxidation of alcohols, etc.) [1, 2]. The most general method of their synthesis is the oxi dation of tertiary amines with
⎯(以前是 O=NR3 或 O → NR3)继续吸引合成、理论和应用化学家的兴趣。它们已被用于化妆品、生物医学制剂以及许多有机反应(烯烃的催化环氧化和二羟基化、醇的催化氧化等)中的氧化剂 [1, 2]。其合成的最通用方法是叔胺与过氧化氢、过氧酸、二环氧乙烷和氧杂氮杂吡啶的氧化作用 [1]。
