SYNTHESIS, 1H NMR, 13C NMR SPECTRA AND CONFORMATIONAL PREFERENCE OF OPEN CHAIN LIGANDS ON LIPOPHILIC MACROCYCLES

Several open chain ligands (polipodands) 3 and 4 have been synthesized introducing short oligoethylene glycol units (-CH2CH2O)mCH3, (m=1,2) on lipophilic matrices represented by cyclic tetra-1 and octa-2 oligomers obtained from the base catalyzed reaction of p-butylphenol or p-octylphenol and formaldehyde. 1H NMR and 13C NMR spectral date have been used to establish the conformational freedom of the ligands, which is important for cation binding studies.

Calixarene phosphate derivative with upper edge full eliminated and lower edge full substituted and preparation method of derivative

The invention discloses a calixarene phosphate derivative with an upper edge full eliminated and a lower edge full substituted. The preparation method includes taking calixarene as a matrix; utilizing8 tertiary butyl groups on the upper edge of the calixarene to be removed under the condition of anhydrous aluminum trichloride and 8 phenolic hydroxyl groups on the lower edge to be functionally modified under the alkaline condition; and adopting a two-step method to prepare the calixarene phosphate derivative with the upper edge full eliminated and the lower edge full substituted. This is a novel calixarene derivative, which has improved the separation efficiency and selectivity of light rare earth ions compared with the original calixarene phosphorus oxide derivative with only the lower edge fully substituted. The preparation method has the advantages of high yield, convenient purification, mild conditions and complete substitution, so that the method is suitable for industrial production.

Synthesis and investigation of catalytic affinities of water-soluble amphiphilic calix[n]arene surfactants in the coupling reaction of some heteroaromatic compounds

Six water-soluble calix[n]arene-based Br?nsted acid-type catalysts with amphiphilic groups were successfully synthesized by incorporating sulfonic acid moieties. Their structures were characterized using FTIR,1H NMR,13C NMR, APT-NMR, and elemental analysis techniques. Moreover, their catalytic capabilities were evaluated in the coupling reaction of 2-methylfuran and/or N-methylindole with some sec-alcohols in aqueous media. The association of their surfactant abilities, and the effects of water amount used and reaction durations on the catalytic activities of these amphiphilic calix[n]arene derivatives were also investigated. Observations indicated that these amphiphilic calix[n]arene catalysts exhibited high catalytic activities in the coupling reactions of 2-methylfuran and N-methylindole with some alcohols in water.
