Alkane oxygenation with H2O2 catalysed by FeCl3 and 2,2′-bipyridine

Oxidation of alcohols with hydrogen peroxide catalyzed by soluble iron and osmium derivatives

“…The maximum turnover number (total moles of products produced per one mole of a catalyst; TON = 135) was also attained under conditions of run 6. In contrast to alkane oxidation by H 2 O 2 catalyzed by FeCl 3 , where addition of 2,2'-bipyridine (bipy) enhances dramatically (up to 40 times) the initial oxidation rate [41], in the oxidation of alcohol 1, the effect of added bipy is weaker. Nevertheless, at room temperature (the reaction time is 24 h), the addition of bipy significantly improves the yields of products and TON (compare runs 1 and 2).…”

“…We have found that simple salt, aqueous iron trichloride (see catalytic oxidations of alkanes with this compound [39][40][41]), in the oxidation of 1 with H 2 O 2 is the most efficient catalyst among all checked iron-containing compounds. The results of the oxidations under different conditions are summarized in Table 1.…”

“…The reactions were carried out both in acetonitrile and without any solvent. In addition, the effects of added diamines (2,2'-bipyridine and phenanthroline) on the reaction rates and product yields were examined, because it is known [41] that such additives can dramatically enhance the efficiency of metal-catalyzed hydrocarbon oxygenations.…”

Silica aerogel–iron oxide nanocomposites: recoverable catalysts for the oxidation of alcohols with hydrogen peroxide

“…According to some reports, the addition of some alkaline species (e.g., NaOH, KOH, NaHCO 3 ) into the reaction system was beneficial to alkene oxidation [52][53][54]. The efficiency of iron-catalyzed oxygenation of hydrocarbons by hydrogen peroxide increases in the presence of amines [55]. In addition, the significant effect of imidazole as a cocatalyst in increasing substrate oxidation by non-heme systems has been reported [56].…”

Fe-Catalyzed Oxidation Reactions of Olefins, Alkanes, and Alcohols: Involvement of Oxo- and Peroxo Complexes

“…In contrary to the not easy adjustable ligand-free systems, systems with ligands provide possibilities in tuning activity and selectivity. Shul'pin et al examined the addition of bipyridine to FeCl 3 and hydrogen peroxide as oxidant [89]. They monitored a 35 times enhanced reactivity (TON up to 400) for oxidation of cyclohexane.…”
