Aqueous Synthesis of 14-15-Membered Crown Ethers with Mixed O, N and S Heteroatoms: Experimental and Theoretical Binding Studies with Platinum-Group Metals

A series of 14-15-membered O, N, and S-containing crown ethers (CEs) was synthesized by cyclization of bis-epoxides with aryl-N or S dinucleophiles using triethylamine as a catalyst and LiCl as a metal template in water. The catalyst dosage, and metal template type and dosage were critical in achieving yields of 56–93 %. Liquid-liquid extraction (LLE) was performed to evaluate the CE complexation with Pd2+ and Pt2+. Among the CEs, a dioxa-dithia dibenzo CE exhibited the highest Pd2+ selectivity even in the presence of other platinum-group metals (PGMs). Complementary DFT studies reveal that this CE has the most compatible cavity dimension (?CE=1.58 ?) with Pd2+ (?Pd2+=1.56 ?) forming a square-planar S4 geometry. Binding-energy calculations showed the Pd2+ complex has the least energy requirement for structural reorientation during complexation. Overall results highlight the importance of CE cavity dimension and presence of S heteroatoms for the structural design of CEs selective towards PGMs such as Pd2+.

Theoretical and extraction studies on the selectivity of lithium with 14C4 derivatives

Lithium is a critical strategic metal for world economy development and is used in various fields, such as daily life, aviation, medicine, chemical industry, etc. Crown ethers can adsorb Li+ from a mixed ionic solution based on the size matching effect and synergistic effects of functional groups. The selective adsorption properties with Li+, Na+, Mg2+ and the interaction between crown ethers and metal ions were analyzed to guide the design of crown ethers with high selectivity for Li+. The geometric structural characteristics of 1,8-dihydroxyl-4,4,5,5-tetramethylbenzo-14-crown-4 (CE) and complexes with Li+, Na+, and Mg2+ metal ions were investigated using density functional theory modeling (DFT) at the M062X/def2SVP, def2TZVP level. The nature and strength of the interactions were analyzed by atoms in molecules (AIM) topological analysis and symmetry-adapted perturbation theory (SAPT) energy decomposition analysis. The results showed that the interaction strength of CE with metal ions followed the order: CE-Mg2+ > CE-Li+ > CE-Na+. The interaction energies can be separated into four kinds: Electrostatics, exchange, induction, and dispersion. The stability of these complexes was mainly driven by electrostatics and induction. According to the analysis results of reduced density gradient (RDG), the metal ions mainly interacted with the oxygen atoms on the ring and did not interact with the hydroxyl groups directly. CE was synthesized and the extraction rates of Mg2+ and Li+ were better than that of Na+. This journal is

Macroheterocycles. Part 42. A Facile Synthesis of Dihydroxy Cryptands and their Dehydroxylation

A facile synthesis of hydroxy cryptands by the reaction of diglycidyl ethers with a diazacrown ether is reported.The reaction results in a mixture of bi- and tri-cyclic cryptands which can be separated by chromatography.The yield of bicyclic cryptands is lowered with a decrease in the diazacrown ether cycle size and an increase in the number of oxyethylene moieties between the epoxy groups in the diglycidyl ether.The results are interpreted in terms of the intramolecular hydrogen bonding of epoxy groups promoting the steric fixation of the reaction centres.Dehydroxylation of the bicyclic dihydroxy cryptands has been performed by means of chlorination followed by reduction.

MACROHETEROCYCLES. XL. DIHYDROXYCRYPTANDS

The condensation of diglycidyl ethers with diazacrown ethers leads to good yield of dihydroxycryptands.The yields of the bicyclic cryptands decreases with decrease in the ring size of the initial diazacrown ethers and with increase in the distance between the epoxide groups in the diglycidyl ethers.It is suggested that the good yields of the cryptands are due to the steric immobilization of the reacting groups in the monoalkylated intermediate.The proposed mechanism is supported by experimental data.Some of the dihydroxycryptands were separated into the D,L andmeso diastereomers.
