Bihanic, Camille;Stanovych, Andrii;Pelissier, Franck;Grison, Claude published 《Putting Waste to Work: The Demonstrative Example of Pyrite Quarry Effluents Turned into Green Oxidative Catalysts》. The research results were published in《ACS Sustainable Chemistry & Engineering》 in 2019.Quality Control of rel-(1R,2S)-1,2-Diphenylethane-1,2-diol The article conveys some information:

In the context of exponentially growing problems of pollution and waste, the design of ecofriendly processes for turning the current treatment of effluents into sustainable catalysts represents a great opportunity. Wastewater arising from pyrite quarrying is selected as a model example. The acidity of pyrite effluents leads to solubilization of useful cations: Mn^II and Fe^II/Fe^III. Their chem. properties are an opportunity to promote innovative studies of oxidation in organic synthesis. The controlled addition of NaOH and a co-oxidant (H₂O₂) onto the effluents allows generation of new, oxidative catalysts. MP-AES anal., XPS, XRPD, BET, TEM, HRTEM, and EDX studies were performed to characterize the new and efficient catalysts. Oxidation of alcs. into carbonyl compounds, oxidative cleavage of 1,2-diols, and epoxidation of alkenes are described. The experimental procedure involved many compounds, such as rel-(1R,2S)-1,2-Diphenylethane-1,2-diol (cas: 579-43-1) .

Reference of rel-(1R,2S)-1,2-Diphenylethane-1,2-diol《Binuclear Double-Stranded Helicates and Their Catalytic Applications in Desymmetrization of Mesodiols》 was published in 2019. The authors were Chinnaraja, Eswaran;Arunachalam, Rajendran;Suresh, Eringathodi;Sen, Shovan K.;Natarajan, Ramalingam;Subramanian, Palani S., and the article was included in《Inorganic Chemistry》. The author mentioned the following in the article:

The ligand L₁ of 4-methyl-2,6-diformylphenol and L₂ of 4-tert-butyl-2,6-diformylphenol were synthesized through Schiff base condensation with rac-, (R)-(+), or (S)-(-)-1,1′-binaphthyl-2,2′-diamine (BNDA). As a result, the racemic L₁^rac, L₂^rac, and enantiopure L₁^RR, L₁^SS, L₂^RR, and L₂^SS ligands were obtained incorporating Cu(II) and Zn(II) salts by a simple one-pot metal template method. The series of dinuclear complexes of [M₂LX₂] (here, M = Cu²⁺, Zn²⁺; X = acetate ion, chloride ion; L = L₁^RR, L₁^SS, L₁^rac, L₂^RR, L₂^SS, L₂^rac) formulas were obtained in common. Among them, the single crystal x-ray structures for [Zn₂L₁^rac(OAc)₂] and [Zn₂L₁^SSCl₂] complexes were obtained. The detailed crystal structure and the chiroptical studies performed on these complexes dictates a self-sorting behavior in their self-assembly process and illustrate a chirality transfer from the ligand to the metal center on the complexes. The enantiopure dinuclear complexes [M₂L^RRX₂] and [M₂L^SSX₂] generate enantiopure ΛΛ and ΔΔ isomers, resp., but the racemic complexes produce only homochiral ΛΛ and ΔΔ assemblies. The detailed studies based on UFLC (Ultra Fast Liquid Chromatog.), CD, and single crystal x-ray structure together show the absence of heterochiral ΛΔ mesocate. All these complexes are adapted as catalysts for desymmetrization of various mesodiols, and the enantiopure complexes give efficient enantioselectivity in desymmetrization of mesodiols with benzoyl chloride to monobenzoylated ester providing 98% yield and 92% ee.rel-(1R,2S)-1,2-Diphenylethane-1,2-diol (cas: 579-43-1) were involved in the experimental procedure.

Huang, Jiuzhong;Ouyang, Lu;Li, Jianxiao;Zheng, Jia;Yan, Wuxin;Wu, Wanqing;Jiang, Huanfeng published 《B₂pin₂-Mediated Palladium-Catalyzed Diacetoxylation of Aryl Alkenes with O₂ as Oxygen Source and Sole Oxidant》 in 2018. The article was appeared in 《Organic Letters》. They have made some progress in their research.Electric Literature of C14H14O2 The article mentions the following:

A novel palladium-catalyzed alkene diacetoxylation with dioxygen (O₂) as both the sole oxidant and oxygen source is developed, which was identified by ¹⁸O-isotope labeling studies. Control experiments suggested that bis(pinacolato)diboron (B₂pin₂) played a dominant intermediary role in the formation of a C-O bond. This method displayed good functional group tolerance with moderate to excellent yields and could be successfully applied to the late-stage modification of natural products. Furthermore, an atm. pressure of dioxygen enhances the practicability of the protocol. To complete the study, the researchers used rel-(1R,2S)-1,2-Diphenylethane-1,2-diol (cas: 579-43-1) .

Category: alcohols-buliding-blocksIn 2017, Escande, Vincent;Lam, Chun Ho;Coish, Philip;Anastas, Paul T. published 《Heterogeneous Sodium-Manganese Oxide Catalyzed Aerobic Oxidative Cleavage of 1,2-Diols》. 《Angewandte Chemie, International Edition》published the findings. The article contains the following contents:

The aerobic oxidative cleavage of 1,2-diols using a heterogeneous catalyst only based on earth-abundant metals manganese and sodium is reported for the first time. This reusable catalyst cleaves a variety of substrates into aldehydes or ketones with high selectivity. The reaction requires small catalytic loadings and is performed under mild conditions using ambient pressure O₂ or air as the oxidant while producing water as the only byproduct. Mechanistic investigations reveal a monodentate, two-electron oxidative fragmentation process involving a Mn^IV species. The eco-friendly, innocuous catalyst is compatible with a wide range of functional groups and conditions, making it highly competitive with classical reagents, such as periodic acid or lead tetraacetate, as a preferred method for activated 1,2-diols. To complete the study, the researchers used rel-(1R,2S)-1,2-Diphenylethane-1,2-diol (cas: 579-43-1) .
