-
Page/Page column 12-13, (2020/12/30)
Process for the production of a diacyl peroxide involving the reaction of an anhydride with hydrogen peroxide, removal of the formed carboxylic acid, production of an anhydride from said carboxylic acid, and recycling of the anhydride within the process.

A facile iron-catalyzed decarboxylative radical coupling of alkyl diacyl peroxides with coumarins or chromones has been developed, affording a highly efficient approach to synthesize a variety of α-alkylated coumarins and β-alkylated chromones. The reaction proceeded smoothly without adding any ligand or additive and provided the corresponding products containing a wide scope of functional groups in moderate to excellent yields. This protocol was highlighted by its high regioselectivity, readily available starting materials, and operational simplicity.

Anticancer active metal complexes with biologically active ligands have the potential to interact with more than one biological target, which could help to overcome acquired and/or intrinsic resistance of tumors to small molecule drugs. In this paper we present the preparation of 2-hydroxy-[1,4]-naphthoquinone-derived ligands and their coordination to a RuII(η6-p-cymene)Cl moiety. The synthesis of oxime derivatives resulted in the surprising formation of nitroso-naphthalene complexes, as confirmed by X-ray diffraction analysis. The compounds were shown to be stable in aqueous solution but reacted with glutathione and ascorbic acid rather than undergoing reduction. One-electron reduction with pulse radiolysis revealed different behavior for the naphthoquinone and nitroso-naphthalene complexes, which was also observed in in vitro anticancer assays.
Detection of Elusive Chloro- and Bromo Substituted Ozonides by Nucleophilic Substitution Reactions

Ozonolyses of 2,3-dichloro-2-butene (4), 4,5-dichloro-4-octene (9) and 2,3-dibromo-1,4-dichloro-2-butene (12) on polyethylene gave the corresponding ozonides 5,10 and 13a, respectively, which could not be isolated or unequivocally identified. Their identity could be proven, however, via substitution of the chloro- or bromo substituents at the ozonide rings by stabilizing substituents and subsequent isolation of the substituted ozonides 6, 11, 13b and 13c. Ozonolysis of 2,3-diacetoxy-2-butene (14) on polyethylene, in dichloro methane and in pentane gave mixtures of 16 and 17 but not ozonide 6.
