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 L1rac, L2rac, and enantiopure L1RR, L1SS, L2RR, and L2SS 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 = L1RR, L1SS, L1rac, L2RR, L2SS, L2rac) formulas were obtained in common. Among them, the single crystal x-ray structures for [Zn2L1rac(OAc)2] and [Zn2L1SSCl2] 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 [M2LRRX2] and [M2LSSX2] 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.
