Novel catalytic oxidations of terminal olefins by cobalt(II)-Schiff base complexes

Mn-, Fe-, and Co-Catalyzed Radical Hydrofunctionalizations of Olefins

“…92 Although this reaction may not see preparative use since ketone and alcohol products are formed in approximately equimolar amounts and in low yield (< 30%), the authors demonstrate with kinetic experiments that this reaction does not proceed through an auto-oxidation mechanism. Subsequent work from Drago and coworkers also explored the reactivity of these pentadentate Co(salen) complexes in the oxidation of phenols.…”

Solvent-free liquid-phase autoxidation of monoterpenes catalyzed by sol–gel Co/SiO2

“…Surprisingly, autoxidation of alkenes in the presence of cobalt complexes has attracted much less attention [20,21,[24][25][26]. In these reactions a free radical chain mechanism is usually suggested and a competition between the abstraction of the allylic hydrogen to give allylic oxidation products and the addition of the alkylperoxy radical to the double bond resulting in epoxide products is expected [20].…”

Crystal structure of 2-[1-(2-chlorophenyl)-methylidene]hydrazino-1-(3,4- dihydroxyphenyl)ethanone monohydrate, C14H11ClN2O3 · H2O

“…These compounds play an important role in the development of coordination chemistry [1][2][3]. Some of the complexes derived from Schiff bases have been found to have pharmacological potential and antitumor activity [4][5][6].…”
