Catalytic oxidation of α-pinene by transition metal using t-butyl hydroperoxide and hydrogen peroxide

Treatment of paper and pulp wastewater and removal of odorous compounds by a Fenton‐like process at the pilot scale

“…29 On the other hand, catalytic oxidation using various transition metal complexes in the presence of different oxidizing agents has been reported. 29,30 The same compounds [(1S)-α-pinene, β-pinene, (1R)-α-pinene and limonene] were present in treated wastewaters but an 80% reduction in their concentration was measured after applying the Fentonlike process at the pilot scale, which indicates that Fenton-like oxidation is suitable for degrading these compounds. The reactions of • OH with α-pinene is initiated by addition of…”

Allylic chlorination of terpenic olefins using a combination of MoCl5 and NaOCl

“…15 CeCl 3 or InCl 3 combined with NaOCl have been reported as efficient systems for allylic chlorination of terminal olefins. [12][13][14][15][16] In line with our continuous interest in the functionalization of natural terpenic olefins, [5][6][7] we report here the result of our investigation on the allylic chlorination using a combination of sodium hypochlorite and molybdenum pentachloride.…”

“…[1][2][3][4] Previously, we have reported that allylic amines, alcohols, ketones and alkoxycarbonyl derivatives can be obtained in good yields by the metal complex catalyzed amination, oxidation and alkoxycarbonylation of some monoterpenes. [5][6][7] Chlorination represents a valuable pathway to produce versatile starting materials that are widely used in synthetic organic chemistry. [8][9][10][11] Chloride compounds can be prepared directly by bubbling molecular chlorine, but the difficulty of handling chlorine gas limits this procedure.…”

Crystal structure of dichloro((S)-2-(anilinomethyl)-pyrrolidine)- palladium(II), Pd(Cl)2(C11H16N2)

“…Their palladium complexes are used as efficient catalyst in anumber of reactions such as green oxidations of alcohols in an aqueous biphasic system [3] and enantio-selective allylic alkylation [4]. Asp art of our research on transition metal complexes and their application in catalytic valorisation of natural terpenes [5][6][7][8][9], and before employing any catalytic procedures, we try to obtain apalladium complex of dichloro((S )-2-(anilinomethyl)-pyrrolidine. The environment of palladium atom is made up of ( S )-2-(anilinomethyl)-pyrrolidine linked in bidentate manner through it two nitrogen atoms, defining af ive-membered chelate ring and two chlorine atoms.…”
